CodeSnip Old Code (SVN)

* Added new methods to TCtrlArranger to move a control to the left or right of a reference control, with optional margin.
* Modified several form and frame units to use the new TCtrlArranger methods.

* Moved all units directly concerned with supporting syntax highlighting into the new "Hiliter" namespace. Some units were further renamed.
* Revised using units to use the new names.

Renamed UUnicodeHelper unit as UEncodings. Modified all units that used UUnicodeHelper accordingly.

Updated copyright date where required on some files modified in 2010.

Merged delphi2010-port branch back into trunk.

Added support for new "nul" and "Visual Studio" syntax highlighter styles to IntfHiliter, UHiliteAttrs and FrHiliterPrefs units.

Changed to make custom colours assigned in custom colour dialog persistent. Colours are read from preferences on activation of the frame and saved to preferences on deactivation.

Amended TPrefsBaseFrame and descendants with additional abstract methods and their implementations to work with re-implemented preferences dialog box. Each frame now provides information needed by TPreferencesDlg to dynamically create the preferences frames and their host tab sheets:
* Index class function determines relative postion of frame in preferences dialog box.
* DisplayName method provides caption of tab sheet that hosts the frame.
* Frame's HelpKeyword property is set appropriately.
* Concrete frame classes now register themselves with TPreferencesDlg in their initialization sections

* Revised code that arranges controls within form or frame to use static methods of TCtrlArranger from new UCtrlArranger unit.
* Removed change logs from units.

Added svn:keywords property with Rev and Date keywords.
