Should be able to also search and install fonts, not only apps

[Simos Xenitellis ]

GNOME Software can only search and install packages which are (probably) marked as GUI applications.
In terms of usability, it is a good choice and the chances to mess up a system are diminished.

As a result, it is not possible to install fonts.
Fonts should also be regarded as packages that can be searched for and installed through GNOME Software.

Reproduce:
1. Start GNOME Software
2. Search for "font"

Expected result: several packages about fonts should be shown
What happened: no packages are found

Fonts in the archive require metainfo files to be added in order to show up in GNOME Software: https://www.freedesktop.org/software/appstream/docs/sect-Metadata-Fonts.html

This isn't really a bug in GS, but rather needs to be an archive-wide effort to add such metadata.

This bug was fixed in the package gnome-software - 3.24.3-0ubuntu5

GNOME Software in Ubuntu 17.10 Alpha now shows the Cantarell, Lato and Oxygen fonts and 11 Lohit fonts for Indic languages. In order for more fonts to show up, similar appstream metainfo files will need to be added to the other font packages in Debian or Ubuntu.
