This reverts commit a1f0872486995b80216e8a08a2176debdef3752a.
As updating handlebars needs some more involvement, we roll back to the
version we use currently and schedule the update for later.

The previous iterator was implemented to simply fetch _all_ pathes from
the filesystem, no matter what.
With this implementation, this changes. The iterator now has
functionality to optimize the iteration, if only a subdirectory of the
store is required, for example `$STORE/foo`.
This is done via functionality where the underlying iterator gets
altered.
First of all, the interface was changed to return a `Entries` object,
which itself only covers the libimagstore-internal `PathIterator` type.
This type was changed so that the backend implementation provides an
"PathIterBuilder`, which builds the actual iterator object for the
`PathIterator` type.
The intermediate `StoreIdConstructingIterator` was merged into
`PathIterator` for simplicity.
The `Entries` type got functionality similar to the
`StoreIdIteratorWithStore` type for easier transition to the new API.
This should probably be removed at a later point, though.
As the `walkdir::WalkDir` type is not as nice as it could be, iterators
for two collections in the store could be built like this (untested):
store
.entries()?
.in_collection("foo")
.chain(store.entries()?.in_collection("bar"))
Functionality to exclude subdirectories is not possible with the current
`walkdir::WalkDir` implementation and has to be done during iteration,
with filtering (as usual).

According to [0] these new settings might help to optimize build times
on travis.
Lets see what happens.

Because we do not use github for development anymore, but still for
travis, we enable notifications so we know whether our builds succeed

It is a simple approach but it works: Read the name of the binary from
the Cargo.toml file and check whether the name appears in the path.

This patch changes the filesystem-backend implementation of libimagstore
to open files on each read/write rather than holding the file handle in
memory at all times.
Whenever a lot of imag store entries are read into memory, the imag
process may ran out of file descriptors. With this patch applied, a
`Store::get()` call on an entry which is not yet in the store cache
would cause the file to be read, but the FD being dropped after that.
Likewise, a `Store::update()` (which is also called if the imag entry is
dropped) would re-open the file on the filesystem and write the contents
from the imag store cache back to the file.
With this patch, opening hundrets or thousands of imag entries should be
no problem anymore, only the available memory should be a limit then.

This patch fixes a bug where entries where created with
`Store::retrieve()` rather than with the API from libimagdiary.
This caused headers to be missing.
Now, the CLI is parsed for the values passed and a NaiveDateTime object
is crafted from that, which is then passed to libimagdiary.
This patch fixes a bug we did not even hit (yet). It is: When deleting
an Entry from the store, this could potentially leave artifacts in the
cache.
Szenario: An Entry, which was loaded (via `Store::get()` for example),
gets `Store::delete()`ed twice. The first call would work as expected,
but leave the Entry in the Store cache. The second call would then fail,
as the Entry is already removed on the FS, but still in the cache. This
would fail - which is the right thing to do here - but with the wrong
error (with a FileError rather than a FileNotFound error).
This patch fixes this.
First of all, the appropriate `PathBuf` object is calculated in all
cases, as this object is needed to check whether the file is actually
there (which could be the case if the Entry is in the cache and if it is
not).
If the entry is in the cache and is borrowed: error. If not, remove the
entry from the cache. Afterwards the file is deleted on disk.
If the entry is not in the cache, but the file exists, the file is removed.
If the file does not exist: error.
