Added in filters for post-natal and emergency visits; TODO make it selectable from a list instead of hard coding it so dinamically changes based on the returned data set; TODO reduce number of calls to the server.

Added all selector; Added computed dates array (WIP).

Filter for date tests.

Add canDelete calculated property; Small improvements on date filtering.

Finally fix the all lookup to use cached results; get the clear filter working to some extend.

Buttons for better viewing pleasure
Added human readable date with moment.js.
Indicate selected date on the buttons.
Priority and Visit type select boxes.
Date and Time input fields for the new appointment added.
Added category filter; TODO display the category names, same applies to SPs and SUs.
Remove extra whitespace at the end of the line.
