Removed vimball install instructions from INSTALL and README files.
Added information on pathogen installation to INSTALL file.
Remove all remainders of localleader munging.

Also
 * fix the documentation to work with Pathogenized plugin
 * explain configuration via vimoutlinerrc

Fixes #41
Move README.detailed to doc/votl.txt to make Pathogen working.
Gramatical and stylistic corrections.

* Fix legay -> legacy.
* The first sentence of "Comma comma commands" section was fixed.
Remove vimball reference.
Update in install.sh so that it installs vimoutlinerrc correctly.
Correct votl_cheatsheet so that it is installed with helptags.
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)
doc/votl_readme.txt is just a copy of old votl.txt, remove it.
