Remove dosbatch.vim because it's shipped with vim

I added this back in 2010 because it was newer than whatever vim shipped
with at the time. Vim 7.3 and 7.4 both ship with this version of syntax,
so don't duplicate it.

I also modified it to remove syntax highlight for one case of
dosbatchLabel -- where the word starts with a label because I was
working somewhere that used :call a lot. I don't anymore and I think
that usage is incorrect, so I'm okay with losing that change. (Also
since the built-in syntax file was loaded, my change had no effect.)
Use indent foldmethod for dosbatch

Since the dosbatch syntax file provides no folding, use indent instead.
Jump to top of selection when refactoring

vai selection ends at the bottom of the indent region, so use 'o' to
move to the top. This way when we do our replacement, there's no jump
back to the top.
Add refactor selection map

New map that functions like normal mode refactor, but for selection.
Same keystrokes: gr

Useful to turn an expression into a variable. No point of definition so
just use indent from textobj-indent. Clobbers @c register.

Inspired by Visual Assist's new introduce variable feature.
sub: Update man to version shipped in vim

This new version shipped in vim7.3, so I'm quite out of date. The
changes are very minor.
Disable OnlineThesaurus in windows

OnlineThesaurus uses a shellscript to get the thesaurus information
and it doesn't work on windows.
sub: Switch online thesaurus to my fork

I've fixed it up to work for me on Windows and to re-use the window.

Update vimrc settings to allow its use on win32.
Don't mess with Ctrl-L in popupmenu

I use Ctrl-L to complete more characters during ins-completion (it's
like the opposite of Ctrl-h). That's also a situation I would Esc out
of, but I could learn Ctrl-Y (to say Yes and accept) and Ctrl-E (to End
and reject) instead.
sub: Fix map in endoscope

C-; does not exist on Windows.
Change default EasyAlign map to include *

My most common use of EasyAlign is to align all fields. Make the Enter
map do that (sets * mode for all fields) and add C-Enter to use the
default mode.

C-CR may not be supported everywhere, but I can drop to :EasyAlign if
necessary.
