Fix for user-defined <localleader> for command mappings.

<localleader>-mapped commands are not dynamic, i.e. existing mappings
are not changed if <localleader> is updated after mappings have occurred.
To fix this, loading of .vimoutlinerrc must take place before the key
mappings.
1. Moved loading of .vimoutlinerrc to before key mappings.
2. Cleaned up comments a bit.
3. Removed the <localleader>,, command that forces reloading of settings.
	(this command points to non-existent configuration files anyway)
