Tor Lillqvist 8e7897588d Rename the basegfx::tools namespace to basegfx::utils
Reduce potential confusion with the global tools namespace. Will
hopefully make it possible to remove the annoying initial :: when
referring to the global tools namespace. Unless we have even more
tools subnamespaces somewhere.

Thorsten said it was OK.
