Removing a lot of now redundant code!

Since creating a more generalized function for rendering the charts
(renderSMCTimeline() and loadSMCSnapList) I am removing the previous
more specific functions.

I like removing code as much or more than adding it.
Moved some prev global vars into this function

I've removed one of the global vars "raj" by moving it inside this
function. Now the function receives a String instead of JSONArray
object. Cleaner.
Removed more code! And replaced a global var by moving it into a function.
Creating chart info globals and making it easier to switch.

To switch between a room based rows and a day of week based rows. By
making this more generic it should be easier to add new chart row types
like "doing", "location"...
Adding functions to access SnapEntry object data
Making generalized data structure functions

Removing functions specific to "rooms" or "days" and replacing with a
more generic loadChartDTCounts(). DT = data type.
