* Remove workaround for Unicode text to and from clipboard
* Fix writing/reading wrong encoded text into/from registry - no need to use Utf8Encode() any longer
* Implement TMySQLQuery.ColAsAnsi() for cases in which we read binary data.
* 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.
* Instead, use separate SHOW commands for tables, functions, procedures and triggers
* Catch this chance to move these methods from main unit to mysql_connection, so they're accessible in a more generic way
* Additionally, introduce new classes TDBObject and TDBObjectList which provide a more generic way than TMySQLQuery to access these database objects.
Fixes issue #1529
* Use this chance to add a confirmation dialog when leaving the editors, to ask the user if he wants to save modifications. Fixes issue #1524.
* Also, enhance Mainform.RefreshTreeDB in a way that it does not trigger the OnFocusChange event. Important for the editors when saving changes.
* This time, also support formatted integers, not only floats.
* Do not quote both types in grid updates/deletes/inserts.
* Do no internal conversion from string to float and back to string (FloatToStr did that) to avoid silent data corruption. Just use strings in all places.
* Replace FloatStr() function with UnformatNumber(), which is also able to handle integers
Should fix issue #1012
* Move const.inc and compilers.inc back to main source directory
* Move remaining few lines of code from heidicomp.pas to helpers.pas
