Upgrade Google Mock to 1.7.0.

Disable building shared libraries, as I got link errors. Static build
works. Will wait to close issue until Mac build is verified.
More GMock files to commit.
Even more?
Uncomment tests on Mac--gmock hang bug is fixed.
Merge branch 'libraryUpdate' of https://github.com/SCIInstitute/SCIRunGUIPrototype into libraryUpdate
Debug unit tests build now. Closes #399.
Merge remote-tracking branch 'origin' into libraryUpdate
Update Eigen to 3.2. Closes #422
