#249 Default fonts doesn't keep through restart

[Tanglor]

Changes set in 'Edit' -> 'Preferences' -> 'Appearance' default fonts are applied and working ONLY after OK button. All messages are displayed with those fonts.
But after restart - fonts return to Times (default initial font) and fonts applied directly inside messaged.

Steps to reproduce:
Change default fonts to 'Verdana' (font from ttf-mscorefonts-installer packet)
Clicked OK to confirm changes
Go through messages to confirm changes (new font is active).
Close NixNote2.
Start NixNote2.
Observe font 'Times' (default installation font).

Further information:
When I set Verdana as Editor Font and System Default as Editor Font size - font TImes is used as default.
When I set Editor font size to some value - after restart fonts are changed to Verdana as expected.
However -> mapping between Editor font size and real font size in notes are broken. To achieve font size 12 I needed to set 16 in preferences.

Fixed in the next release.
