Check shell in Windows before assuming cmd.exe

In Windows, some users set the Cygwin shell as their Vim shell, make
Vundle consider this when deciding which flavour of commands to run when
cloning. Roughly check if the shell contains `sh` in it, and assume a
Unix shell, even when on Windows.

Resolve symlinks before running helptags

Fix #374 shellescape problem
Fix shellesc()
Some documentation fixes and changes

1. Fixed some lines which were wider than 78 characters.
2. Added a couple of more borders above all the sub-sections.
3. Moved about part above the TOC, seems unnecessary to have that as its
own section when it's so small. This also look more like a  default vim
help file.
4. Changed "NOTE:" into "Note that" because that is more like how it's
used in default vim files.
5. Changed some wording like "the plug-in manager" to "a
plug-in manager".
6. Moved a couple of *tag names* below their headings so it's like that
everywhere in the file.
