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.

This patch also removes the (unused) "compile" subcommand and replaces
it with a flag "-c" / "--compile" which prints the output in formatted
to the terminal.
Compiling the output from markdown to HTML and showing in the browser is
not yet possible.
The imag-view command was redesigned with this change. It now looks up
view-templates in the config and calls them with the "in" subcommand.
This way, an entry can be viewed with editor, browser or whatever one
likes.
Compiling markdown is not supported yet.
This patch removes unused crate imports reported by newer rust versions.
Some crates were only required for tests, some only for tests with
macro_import - these things were fixed with feature gates.
