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.

* `imag-counter` and `libimagcounter` was removed.
|

* `imag-mv` was introduced
|
||||
* `imag-view` uses positional args now
|

* `imag-view` uses the configuration file now to find the command to call
|

for viewing the entry. This way one can view the entry in an editor or the
