The `~` caused docker commands to error with the following:
```
$ docker images
Could not read CA certificate "~/.docker/machine/machines/dev/ca.pem"
```
Switching to $HOME fixes the issue
- Git prompt now indicates when remote tracked branch is "gone"
- New env var (SCM_GIT_DETACHED) that indicates when HEAD is detached
- New env vars available for themes (SCM_THEME_BRANCH_TRACK_PREFIX,
SCM_THEME_BRANCH_GONE_PREFIX, SCM_GIT_DETACHED_CHAR)
- Refactor of git_prompt_vars function from base theme
This plugin adds completion to aliases, just as with their regular
commands. Example:
* Completion works for `git checkout <TAB>`, which shows available
branches.
* You have an alias like `alias gco="git checkout"`
* The plugin adds support for `gco <TAB>`, which will also show the
available branches.

Some functions were specific to OS X, but were defined in the `base` plugin. I have moved them to the `osx` plugin:
* pman
* pcurl
* pri
As for `pcurl`, the `osx` plugin already had an existing `prevcurl` function, which was doing the same thing. I've aliased `pcurl` to simply call `prevcurl` to avoid breaking existing installations.
As far as I know the `open -fa $PREVIEW` thing only works on OS X, which means that these functions have only worked on OS X anyway.
A set of functions to simplify listing OS X Time Machine backups, and
deleting old ones. Pulled from various script solutions found on Stack
Overflow, adapted to the Bash-it framework.
The functions allow to show which backups can be found on the connected
Time Machine volume. The 'delete' function allows to safely remove all
backups except for the latest one - this can be used to free up space on
the Time Machine volume. The 'delete' function uses functionality of the
OS to safely remove the old backups, no information is lost.
The 'delete' function will only ask for the password once, then keep the credentials.
