* Removes TNT Unicode controls, which are no longer required. All VCL controls now have native Unicode support.
* Remove Delphi 11 packages, otherwise we would either need to keep TNT or break Unicode
* PngComponents update from Uwe Raabe on http://cc.embarcadero.com/Item/26127
* Adjust auto build process
* Since Delphi 2009, Strings are now UnicodeStrings, not AnsiStrings any longer. Fix a bunch of compiler errors which came along with this change.
TODO: Project should compile but give tons of compiler warnings.
* Add a batch file which installs design-time components.
* Bugfix build_super; going to the end of a batch file to exit it when inside a batch procedure does not work.
* Rename batch scripts so they appear in the directory in the order they are to be used in (1. compile, 2. install ide components, 3. generate installer relevant stuff).
This tool only modifies 'Known Packages', 'Package Cache' and 'ToolForm/Mapping' are left untouched (since it would be a bitch to muck with those).
Seems to work fine in BDS 2006, everything is listed correctly in the tool palette etc.
