[vim] moved vim-notes folder to ~/Documents/
[zsh] check if we aren't running inside tmux already.
[vim] use the Ubuntu Mono font by default for GUI.
[vim] move all temp files over to the .vim directory.
[zsh] add $HOME/.local/bin to PATH if available.
[ssh] disable ssh connection mulitplex for now.

it doesn't work well with flaky connections, and makes it harder to
debug new server configuration (authorized_keys).
[ssh] added hosts for codilime internal stuff.
[ssh] enabled ssh multplexing for github and bitbucket.

if there are connection issues with those, it's not really going
to make debugging any harder.
[ssh] make sure that $HOME/.ssh/controlmasters/ exists.

ssh doesn't like it when the folder is missing and you are trying to use
connection multiplexing.
[bin] pass tweaked to support nested git repos.

pass [1] doesn't know how to handle nested password-stories wrt keeping
changes in separate git repositories (one for work, one for private
stuff for example). This is a modified binary that adds this feature.

[misc] fixed .gitmodules file.
