Vim: Remove delimitMate

Prep for installing autopairs.
Vim: switch to using Input as the GUI font

This is our special version, customized to have a 1.3x line height, and
have the Powerline symbol glyphs added.
Vim: make indent guides on by default + other cfg

We also tell indent guides to not turn on for nerdtree windows, and to
only start on the second level of indents. (The 'guide size = 1' was
already there, we just moved it around.)
Tell ctrlp to ignore node_modules directories
Vim: (disabled) to turn JS keywords into symbol

We add in config settings that turned some JavaScript keywords into
symbols in Vim's UI (like turning "function" into the mathematical
function symbol.) We also add better highlighting of these symbols to
jellybeans+'s colorscheme.

We currently have this functionality disabled (by commenting out
"conceallevel=1" in the javascript filetype autocmd,) but this could be
turned back on easily.
Vim: leave out file frmt, encoding from powerline

We also tell it to give higher priority when drawing the file type, and
lower to the vcs branch (used when the line is too short to draw
everything, and it has to choose.)
Vim: add auto-pairs plugin
Bash: add anaconda to path (disable for now)

I need to investigate if/how it might interfere with my normal Python
install, installed packages, etc. before enabling.
Bash: a couple misc. .bash_profile cleanups

We remove the SPIDEROAK_UI_STYLE setting, which never seemed to work.
We also make sure to export the $PATH when we're done setting it.
Bash: add pyenv, pyenv-virtualenv to path
Bash: (intelligently) add npm local bins to PATH

When we're in a directory (subdirectory of a directory) that has
non-global npm modules installed, add the node_module/.bin directory to
the path while we're in that directory/subdirectory (and remove them
when we leave.)
Bash: add alias `bashrc` to edit .bash_profile

The alias `bashrc` will open ~/.bash_profile in mvim for editing.
Vim: disable auto-pairs centering line on insert

Previously, when auto-pairs inserted some text, it would move the
current line to the center of the screen (vertically). This setting
disables that.
Vim: delete buffer holding session file on start

Adds an autocmd on VimEnter which runs a function that will check to
see if vim-session reports that there's a current session. If so, it
finds the path to the session file, and deletes any buffers holding
that session. This keeps our buffer listing clean.
Vim: change CtrlP key mappings
Vim: add 'vim' to filetype we auto-trim whitespace
Bash: add alias `defs` -> `defaults read`

Easy way to print out OS X preferences. The dual, `defaults write` is
used rarely enough by me that I can type it out long-form when I need
to use it.
