* PageEx - every page can be used everywhere and as many times as needed

* DirVar - easy way to add another dir page
* default strings in the language file (Page directory is enough, no need for DirText)
* strings from the language file are now LangStrings that can be used in the script
* no more /LANG - one string for all languages
* any lang strings can be used everywhere, installer or uninstaller (no un.)
* no more unprocessed strings - variables can be used almost everywhere (except in licenseData and InstallDirRegKey)
* DirText parm for browse dialog text
* SetBkColor -> SetCtlColors - can now set text color too
* fixed SetOutPath and File /r bug
* fixed File /a /oname bug
* added $_CLICK for pages
* added quotes support in lang files (patch #752620)
* extraction progress
* separate RTL dialogs for RTL langs (improved RTL too)
* InstallOptions RTL
* StartMenu RTL
* fixed RegDLL?
* added IfSilent and SetSilent (SetSilent only works from .onInit)
* fixed verify window (it never showed) (bug #792494)
* fixed ifnewer readonly file problem (patch #783782)
* fixed wininit.ini manipulation when there is another section after [rename]
* fixed some ClearType issues
* fixed a minor bug in the resource editor
* fixed !ifdef/!endif stuff, rewritten
* lots of code and comments clean ups
* got rid of some useless exceptions handling and STL classes (still much more to go)
* lots of optimizations, of course ;)
* updated system.dll with support for GUID, WCHAR, and fast VTable calling (i.e. COM ready)
* minor bug fixes
