Feature: Update Jeff Felchner approved colors for iTerm beta
Bugfix: Move 'less' options into an environment variable

Previously even though we were setting the `PAGER` to `less` and setting
an alias of `less` to `less` plus the default options that we wanted,
the `PAGER` was not using them.

Fortunately `less` looks for an environment variable named `LESS` which
it will pull default options from.
Feature: Don't install gpg by default

On Macs, it's better to install MacGPGTools which has access to the
keychain, a preference pane and other niceties which allows the
`gpg-agent` to effectively only have to prompt you once for you key.
Any subsequent accesses will be pulled from the keychain.
Bugfix: When checking for process names, only match full names
