[Continuous Integration] Jenkins Daily Build Tasks

[dilijev]

Add additional build tasks which will only run once per day but will test additional scenarios.

Daily task for each of [ {x86,x64,arm} x {debug,test,release} ] which are done for every commit to master and every pull request. These tasks use Windows Server 2012 R2 + VS 2015 (the default configuration of windows build machines).

Additionally, daily tasks for [ {x86,x64} x {debug,test,release} ] running on Windows 7 with VS 2013 (our earliest supported build configuration).
