Changed g:notes_directory to be same with old note taking plugin.
Added <Leader>g mapping like the <Leader>s counterpart, but with g power.
pastetoggle key changed to <F12> since <F11> is somehow not pushing key event to VIM. Lost somewhere in between or some other wreck. Safer to change it than understand it.
'paste' is toggled in normal mode as well. These mapping has the advantage to show the 'paste' value after inversion.
Minor, alignment.
Longer expression is merrier.
Deleted unnecessary maps of which main purpose is to disable default non-sense mapping.
Move function's on top of the file to bottom, where they belong.
Move plugin configuration lines to better place: created a misc area for trivial configs.
Removed <silent> attributes from <F12> <-> :set (no)paste mappings to be able to show the result on screen.
nmap expression shall not be preceded by <Ctrl-O>, since it has different semantics in normal mode than in insert mode.
