Add support for settings from user profiles.clj

[sashton]

It appears that the user profile -- ~/.lein/profiles.clj -- is not used for setting repositories/local-repo/mirrors when executing scripts. If I have a custom local repo set in profiles, and I lein install a custom library, I am unable to refer to it in a script, since it can't be found in the default repositories.

Also, at work I have to specify mirrors for repositories. I've already done that in ~/.lein/profiles.clj, and it would be un-DRY if I had to specify the correct repos in every script, rather than a single profiles.clj file.

If I have a non-default local-repo setting in my profiles.clj, and I somehow configure my script to refer to it (not sure if that's even possible), I can't share my script with a team member who has a different local-repo location.

Example:

~/.lein/profiles.clj

{:user {:local-repo "/custom/location/.m2/"
        :plugins [[lein-exec "0.3.4"]]
        :mirrors {"central" {:name "central"
                             :url "http://my.corp/central"}}

Then running:

$ cd ~
$ lein new app cool-library
$ lein install
Installed jar and pom into /custom/location/.m2/.

~/some-script.clj

(use '[leiningen.exec :only (deps)])
(deps '[[cool-library "0.1.0-SNAPSHOT"]])

Trying to use the dependency

$ cd ~
$ lein exec example.clj
