Bump the version number on Master to 0.7.4

Daily builds are going to run ahead of release build because it has more
than what's there in release branch. Hence RC branch will have version
0.7.3 whereas daily builds will have version 0.7.4
Merge pull request #2902 from Conceptual-Design/master

version number changed to 0.7.4
