Warnings work

TeamCity caught this, but I thought the error was from my warnings
work. Turns out it was a real build failure. Windows doesn’t know which
floating point floor to use. In reality the parentheses are in the
wrong place and should be the floor of the divide by 2. But integer
division is always floor, so it’s not needed at all.

This reverts commit edba7fa8aef832661b33d85109d0bfdf51d024d2.

Pulled fixe from latest eigen across. Figured it was safer to patch
than to pull across whole new version of eigen.

Always evaluated to false due to signed/unsigned

Delete of last link would cause crash. Need to check for -1 which
signals no selection in combo box.

Not sure what qmake # escape is. So fixed the problem instead.

Causing my TeamCity builds to fail

Project file cleanup

Also fixed a number of other release build problems

This reverts commit fcfb392e.

Still not working fully but more information is getting in there than
before. Also by removing VERSION from .pro it fixes problem with vs
proj being built incorrectly.

Made them more understandable for what is needed and for why. Removed
duplication and made sure builds used common settings across all OS
flavors. Removed mingw support for Windows since it was only partially
implemented.
