This commit adds integration to external image viewers and video players
to allow users to view image and video attachments.
Enbas creates a cache directory where the media is downloaded to before
opening the external program for viewing.
Users can view one or more media attachments from a single status.
Now that muting and unmuting accounts are now supported in GoToSocial
(as of version 0.16.0) Enbas can now allow users to do that.
Users can also see a list of accounts that they've muted.
Add a new internal printer package for printing resources to the screen
or pager.
With the new printer in place, most of the settings such as the pager
command, colour theme, whether or not colour output is disabled, etc
are defined in one place which saves us the trouble of passing an
increasing number of parameters to an increasing number of Display
methods throughout the code base.
The old Displayer interface and associated Display methods in the
model package are removed as this is now handled by the printer.
The format functions in the utilities package has essentially been
rewritten as methods to the Printer type.
Additional changes:
- All indentation when displaying information about resources (e.g.
statuses, instance, accounts) are removed.
- The application's build information now has colour output.
