Almost complete the i18n system, including:

Copy unifont..ttf.gz from source tree to target datafile path( now ONLY works with cmake );
Set the locale the same with system's setting;
If need unicode font, unzip and load unifont when init ui styles;
Apply gettext() to labels in space_info.py, who are the main menu items.

Each of these should have been commit one by one. As they work well according to my tests, so I just lazily send a long list.
