Subject: fix COIN3D_MICRO_VERSION regex for coin 4.0.10

In cMake/FreeCAD_Helpers/SetupCoin3D.cmake, the version of Coin3D
we're builing against is extracted from Coin3D's header files via
regexes - but the regex only accepts single digit versions. That
might be fine for COIN_MAJOR_VERSION (currently 4 and increasing
only rarely) and COIN3D_MINOR_VERSION (which is 0 for some years
now), but with the release of Coin3D 4.0.10, we should catch all
digits in COIN_MICRO_VERSION (now at 10), else the build against
the new Coin3D release fails with
: CMake Error at cMake/FreeCAD_Helpers/SetupCoin3D.cmake:79 (message):
:   Coin3D version 4.0.1 mismatches Pivy Coin3D 4.0.10.
