Converted to use Javascript API key

Now uses the UserVoice javascript API key for it's configuration as that is more manageable.

Adds config for uservoice src

You now must configure the uservoice src using the $userVoiceProvider.

Fixes bower main

Bower main had incorrect references. Fixed now.

Restructured src directory

Source code is now properly located under the src directory.

Fixes randomly failures

UserVoice would sometimes not initiate because our references to UserVoice in the service would break. All fixed now!

UserVoice loading added

The directive now fully handles the loading of UserVoice and makes it injectable so it can be used properly by angular modules.

Added identify parameter

You can now set the UserVoice identify by using the identify attribute.

Added position option

Added position option and mode is no longer required (defaulted to contact).

Initial Release of directive

First release of the uservorice-trigger-directive.
