Fullscreen Margins plugin for Gedit

The plugin adds margins around text in the fullscreen mode. This makes text centered in a column with a comfortable width of around 80 characters. By avoiding too long lines, it allows to turn Gedit into "distraction free editor".

Installation: Copy files fullscreen_margins.plugin and fullscreen_margins.py to ~/.local/share/gedit/plugins and enable plugin in Gedit preferences.
