Calendar mode with EventSource Service

[SchizoDuckie]

I made some patches here and there to create a proper angularjs calendar directive that supports showing events on a calendar like the crappyheavily bloated, jquery and jquery-ui-based angular-ui calendar.

Since event templates are most likely something you want to customize I made this an external template, this also allows for binding ng-click events from outside the directive without going through too many hoops.

I've included a standard event service and defined a minimal api to start with.

It could still use some polishing probably, but please take a look and see if you want to merge it. I'll send a pull request from my branch.

@SchizoDuckie I want to keep this module as small as possible. The features you proposed could be provided in a separate module. The following should provide a way to implement the same thing using custom templates
