Trying out vim-fugitive for git integration.

Add a "// ====" header mapping with <Leader>/=, it complements
<Leader>#= but for C style commenting.
Improve jumping around in netrw with some mappings.

<Leader>e. edit . = Take me to the current working directory.
<Leader>E :Explore = Take me to the directory this file is in.
<Leader>re :Rexplore = Take me to the last netrw listing I was in, or if I'm in a
listing take me to the last file I was editing.
