Allow localized display of date/time

I tried to display the date in Spanish. So, I inserted this line

    setlocale(LC_TIME, "es_ES");

in gource.cpp, inside

    void Gource::updateTime(time_t display_time) {

then built and installed, but date is still in English. I know the whole 
compile/install process is working because I have tested other [unrelated] 
changes and they worked.

Alternatively, gource could perhaps obey the global locale setting in one's 
system.
