* The info box in the class doc page is now only shown if javascript is created; this makes the reference guide more suitable for e.g. TGHtml but also links/lynx etc. Achieved by writing the info box with javascript.
* With !=1 as the third argument to THtml::MakeAll(), THtml will use a thread pool when generating the documentation. Added the necessary locks. Threads cannot create TCanvases which is a problem for TDocDirective; this remains to be fixed. As in: WARNING: don't pass numthreads != 1 if you have a TDocMacroDirective or TDocLatexDirective!
* Fix constness of a few functions.
* Don't put $ROOTSYS in front of module's source path
* Fix a string index ==-1 problem in TDocParser::LocateMethodInCurrentLine() discovered with TMath
* TDocDirective: don't delete returned objects if gPad has changed - it might be part of the TCanvas and thus deleted when deleting gPad.
* Add a few gVirtualX->Update()s to reduce the amount of X11 errros.
* Use ':' as the macro path delimiter, even on Windows.
* Only initialize the graphics libs if needed.
* Hack to change the new DeclFileName()s for ROOT from include/Whatever.h to module/inc/Whatever.h, so ViewCVS can display it.
* Hack of hack to fix the DeclFileName() for TMVA.
* Increase the font size of pre blocks; they were too small with TTF on linux.
