Merging fixes and enhancements into trunk.

Revision: [2257]
Refactored cache code in view class.
Removed adding the timestamp to the file contents, it is now
added to the file name

Revision: [2256]
Refactored cache checking code.
Time stamp is not added to file name so we check this 
instead of reading the file and finding timestamp

Revision: [2255]
Adding clearCache function to delete contents of cache
