* Switch order of "apt" and "aptitude" for detection

"apt" is installed by default at Debian (maybe Ubuntu too), while "aptitude" does not seem to be installed by default.
For that, it may be better for most of the users to prefer "aptitude" if installed.

* plugins/debian/README: Change of order mirroded into documentation

Add a new function to get the current mercurial bookmark which can be
used in the theme prompts for example.

Add an alias for ```showpkg``` to get the reverse and recursive dependencies on a package

* add isodate plugin

Download, extract, and cd into the resulting directory.

* Test only for the presence of a .git directory in virtualenvwrapper

Instead of using both $(git rev-parse --show-toplevel) and a check for
a .git directory, use just the latter. As well as being redundant
the former does not work quite so well when using multiple worktrees;
each worktree will be treated as a separate project.

* Unset ENV_NAME & deactivate if no virtualenv found

This addresses #4603 without breaking current behaviour (where current
behaviour is correct).

When changing directories, if there is no environment matching
ENV_NAME, ENV_NAME is emptied and deactivate called if there is a
current environment active (based on CD_VIRTUAL_ENV).

* Use path comparison not string comparison for paths

This will solve part of issue #4255 where WORKON_HOME is defined with a
trailing slash or not normalised in some way, as well as instances
where symlinks are used, and any other instances where constructed
paths don't exactly match even though they go to the same file.

* `rdmd` is aliased to `rake db:migrate:down`
* `rdmu` is aliased to `rake db:migrate:up`
* These tasks allow you to run a specific migration up or down by
specifying the appropriate `VERSION` env variable, which contains
the numerical prefix of the migration's filename

* add: explore alias quickly with aliases plugin.

* change: add compatibility with python2 & python3.

- add compatibility.
- add termcolor.py.
- remove aliass(search), just use acs.
- detect python.

* ssh-agent: lock this script with a mkdir style mutex

This script is a kind of singleton pattern and is not reentrant.
If several shells are oppened in a fast sequence, then several
independent ssh-agents would be created, which is not acceptable.
A mutex is required.

* ssh-agent: only start agent if .ssh dir exists

To use the same profile system-wide, it might happen
that the .ssh directory does not exist
(typically $HOME/.ssh/). This would trigger a error.

Creating the directory would be a option, but it
usually will not make sense to do so because it means
the user doesn't have ssh keys or config.

Option is documented on updated README.md

This commit fixes an issue where the prompt symbol is white when vcs_info is displayed in the gentoo theme.

By default, cargo provides alias for some commonly used functions. This patch
makes it that those alias will complete the same as their full commands.

Default alias:
b -> build
c -> check
t -> test
r -> run

Since cargo allows users to define custom alias it would be nice if
oh-my-zsh automatically detected those and preformed completions as such
but that would be a much more complex patch.

`pk-command-not-found` doesn't accept `--` as an argument. This is what happens when `--` is the first argument:

```
$  gem
zsh: --: command not found...
```

As documented in the README, `npm i -f` forces npm to install the specified packages from a remote
package registry, even if local copies exist on disk caches.
