Fix missing on and off labels, add knob-labels, plus tests.

[Hypercubed]

Ok, let's try again. This should be clean. Forked from your master.

Changes:

1) Added .bowerrc. Bower was not using the correct directory on my machine because a .bowerrc file was found in a parent directory. 2) Fixed issue when labels were not specified by using attr. instead of $scope.. 3) Added tests for default labels. 4) Added knobLabel and tests.

i believe .bowerrc should be put in your project's repo not the library's.

Yes, but Karma is looking for angularjs in the angular-toggle-switch directory. bower install, even when run from the /angular-toggle-switch sub-directory is putting the dependencies in the project directory.

Here is an example of how I think this is fixed. Perhaps there is a better way? I guess you don't see this problem if you are not running karma under your project directory.

myproject
+- .bowerrc                    <-- This tells bower to put my components into ./bower_components below
+- bower_components                           
    +- angular-toggle-switch/
        +- components/         <-- Karma looks for angular here
        +- .bowerc             <-- I think this is needed to make sure `bower install` in this directory uses ./components

I run tests using 2 consoles. One runs grunt watch and the other runs grunt karma:unit. Is this how you are running tests? Are you working on this within another project?

[Hypercubed]

Basically, because I am building and testing angular-toggle-switch within another project I need .bowerrc to isolate angular-toggle-switch from the project. I didn't think there was any harm adding a .bowerrc. Feel free to reject it.

I want to get your knob code in. Can you cherry pick that onto a new branch and make a new PR? We can then work through the default attrs stuff on another PR.

Default labels are now fixed in 8fabe8216cab54a5c72f34d87986d5aa771618ce

Great!
