Implement maxRecents and fix TaskPersister bug 

Activities can now set the maximum number of times that they will
appear in the recent task lists when using DocCentric mode. The
default number is 15, the min 1, and the max 100.

Also a bug in TaskPersister that deleted files because it did not
properly parse their task ids is fixed.

Fixes bug 13736052.
