[Git] Add of some jasmine tests

[lgiraudel]

Add of some jasmine tests to check the HTML output.

The tests can be executed with gulp test or automatically with gulp watch.

Thanks bro.

[apfelbox]

Thanks! I am currently working on a test environment, too, but want to make it a little bit more comfortable and automated, so that it is very easy to add new test / alter existing tests.

I will come back to this in the future - as soon as I have a working prototype.

Wouldn't it be nicer to pass the global Prism variable here?

And add it as an argument for the anonymous function?
This way, you would have a fixed and static dependency on Prism.

@lgiraudel if you split this PR in two (one with the git language changes and one with jasmine testing), I could merge the git one right away.

In general, please people, do not submit multiple changes on the same PR. It’s also in the readme:

Please try to err towards more smaller PRs rather than few huge PRs. If a PR includes changes I want to merge and changes I don't, handling it becomes difficult.

(Btw @apfelbox we need to change the readme to mention that contributors can also merge PRs, as it still says that merging PRs takes ages because it was written when only I could do it.)

Is there a reason why you used Jasmine instead of Mocha? I don't intend to start a flame war but am just wondering since Mocha is a lot more popular (1620 vs 302240 npm downloads in last week)
