* Enhance the TComboBox used in fieldeditor to support option groups via owner drawing.
* Add some ridiculously dumb functions to translate between the dropdown's index and (non-group) item index.
* Accomplishes rfe #577.
I have a slight feeling that this change fixes at least one access violation in the last nightly builds which I cannot reproduce when I compile these changed files.
- Ban glyph data of all TSpeedButton's + TBitBtn's out of dfm files by converting them to TPngSpeedButtons and assign an image from PngImageListMain at runtime.
- Add "highlight" versions of "database" and "table" icons and use these on selected DBtree nodes.
- Remove no longer used BMP icons
Todo: Fill PngImageListMain at runtime.
Note 1: TBitBtn's are not Windows-theme-aware, even with a manifest in place, so we should avoid using them anywhere.
Note 2: T(Png)SpeedButton lacks a TabOrder property, so some of the other TabOrder's are automatically changed here.

+ Use modal result values on buttons instead of explicitely setting them via code
+ Move some safe code out of a try .. except because only THandledSQLError's are catched.
Wrote a small console app which removes these properties automatically in a given directory. Feel free to download it at http://www.heidisql.com/files/explicit_sucks.exe and use it before committing *.dfm files.
