Squashed 'moose-core/' changes from b8a8b6d..74b43c3

74b43c3 Enabled travis emails to developers for this release branch.
76bf854 Related to #169 Dropped the support for VERSION file. 1) It would cause lot of merge issues if VERSION file is left in source tree.
00ea9d3 Close #169. Renamed MOOSE_VERSION to _MOOSE_VERSION.
da0db90 Changed MOOSE_VERSION to __VERSION__ since new cmake 3.7.1 sets it to empty. See cmake policy CMP0048.
