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.
* Moved the location of key mappings to allow for a user's own
  vimoutlinerrc file can change <localleader>. This was necessary
  because keys mappings with <localleader> are not dynamically
  modified if <localleader> is modified after the mapping.
* Commented out the <localleader>,, command - it is very old, points
  to a nonexistent file and is very probably never used.
* Cleaned up some comments formatting.
