Add some new recipes.

Add few el-get recipes.
Could you add them to main recipes repository, please?
Feel free to fix or modify, if you found any mistakes.
Many thanks!
The `:features` directive will cause el-get to `require` the package during initialisation (Emacs startup) so there is no need to also have a `:load` directive.  The downside of having either `:load` or `:features` is that the package is forcibly loaded regardless of whether the user wants them or not, the `autoload` on the other hand means that the package can remain unloaded and the first time someone or something calls the functions registered with `autoload` Emacs will automatically load the package for you.

For an example of this you can check the `bitlbee` recipe.  The difference between the two autoloads in this file is that the first autoload is for a non-interactive function (not callable using `M-x`) and the second one is interactive.
