tweak(client/server): gamemode

[PsychoShock]

• Add locale for every language available in GTA
• Standardize code
• Local some functions
• Change some prints method to trace correctly
• Remove shared file (since config is shared)

When statebags will be re-write, I'll re-do the code entirely but this a "good" thing for now.
