Added TaskQueryRepository (#5)

* Changed the deploy button in README.md to open in a new window

* Added Task.object with 1 sample field set, MyFieldSet, containing a few standard fields

* Added 'without sharing' to LeadQueryRepository.cls

This should be tailored to fit your needs

* Created TaskQueryRepository.cls - it mirrors the lead repo, with a method to get tasks by WhoId

I also removed the comments that exist in LeadQueryRepository.cls - no sense in duplicating/maintaining the comments in 2 places

* Went ahead and added 'without sharing' to QueryGenerator.cls as well
