Add --save-dev option to install command

[satazor]

Now that @desandro added devDependencies, it would be nice to have --save-dev flag for installing and saving directly to devDependencies instead of dependencies.

bower install a --save -d ?

[satazor]

@Nami-Doc -d? I suggested --save-dev to be in sync with npm.

[sindresorhus]

npm uses -D as a shortflag for --save-dev

[satazor]

Alright, didn't know that :D

[satazor]

I've implemented the --save-dev flag, but there's no tests for it yet. In fact there is not tests for --save. Going to add them later.

Status on this? I'd really like to have this soon.

[satazor]

@btford the --save-dev is done and will be available in 0.8.0. I didn't yet find time to do the tests for the --save and --save-dev. If you find some free time, feel free to make a PR with the tests to speedup this.

[satazor]

Done, also added the same for the uninstall command.

[btford]

Awesome work as always. Thanks, @satazor!

bower help shows no sign of this. I had to google it, and it has been around since 0.8... :(

I didn't even see --save (without the -dev) in the help guidelines.
