Major update
- modules content is now being loaded via ajax,
- menu is being reloaded via ajax,
- added functions for handling:
- single menu node reload (by name),
- page main content reload (by url),
Information
- this update does not fully replace everything with ajax load, some forms are still being loaded normally by standard php calls,
- upload form is going to stay like it is now, i'm not planning to make it ajax based upload,
