The ability to install a font theme theme via. drag'n'drop

Installing font themes is the hardest thing to do for new ubuntu users. You have to copy the font files into the directory either in ~/.fonts or /usr/share/fonts . Fonts are also one of the most important features, if you want your desktop to look nice, so in order for ubuntu desktops to look nicer, I suggest that we add "Font Themes". It should work similar to the installation of icons or normal themes.
