Player implemented, and some fixes and tweaks:

+ Player implemented an moves
+Added HUD GUI, which shows life of player
+ Added mod-loading time count

* Log files now work as they should. Latest log should always be log-0.log
* Block textures are now 32x32, 16x16 made fps die
* Error state prints stack trace now, not just error message
* Login system works better
* Couple tweaks to base WaywiaState
* I18N works correctly, added locale test-file en_US.lang

Note: Localization files:
- Should be under "basedir/locales", where basedir is the base directory of the game
- Should either end in ".lang" or ".lang.xml". The former will be parsed as regular Properies file, while the latter will be parsed as xml Properties file.
- The name of the file (without the extension) must be readable with Locale.forLanguageTag(filename).
- If the name of the file contains underscores, they will be replaced with hyphens, so that for example en_US can be used, along with en-US
