Remove obsolete .VimballRecord file.
Remove Align plugin.
Add Easy-Align plugin (replaces Align plugin).
Change indentation for backslash continuations in Vimscript.
Adjust indentation of existing backslash-continued lines.
Update CtrlP.

The new maintainer has incorporated my tag centering patch, so we no
longer need to patch CtrlP.
Update UltiSnips.

My upstream patch has been accepted, so we no longer need to patch it
locally.
Switch BufMRU mapping to <C-6> instead of <Space>.
Switch sneak plugin keymap to <Space>s and <Space>S.
Merge branch 'upgrade-ctrlp-and-ultisnips' of https://github.com/jszakmeister/vimfiles
Use <Leader>a instead of \a for Easy-Align mappings.
Add <Space><Space> as additional keymap for BufMRU mode.

This is aimed at preserving the muscle memory of the original
single-<Space> mapping while retaining the use of <Space> as a leader
key.
