0027237: genproj file does not take into account any arguments

Arguments of genproj tool are revised:
* -path option eliminated (current directory is always used);
* IDE should be always indicated by first argument (instead of -target=<ide> option);
* second argument can be used to specify non-default platform (wnt, mac, lin, ios, qnx);
* option -h, -help, --help can be used to get help
* option -static can be used to build static libs with XCode

README.txt and docs on building are updated.
codeblocks.bat is corrected to be able to detect 32-bit installation of Code::Blocks on 64-bit Windows.
Remains of support of OpenCL (obsolete) are commented out in genconf.tcl
genproj.tcl will not copy env.bat if it already exists.
