Showing tweets on Map

1) A new gis_location record is created for every tweet and a foreign key is stored in msg_twitter_result table for every tweet. 

2) When we use CRMT template, in order to see a menu for 'Twitter' in Explore Community Data Drop down, I have made changes in config.py of CRMT template.

3) In order to add a new entry under overlays section for 'Twitter' , I have added entry in 'gis_layer_feature.csv'. The marker for tweets is set to be that of the icon of 'Twitter'.
