CodeSnip Old Code (SVN)

* 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.

Removed all "do not localise" comments.

Standardised format of Assert statement: all classes use ClassName method for class name and routines use routine name. Records have record name as literal.

Created new IsValidDecimalNumberKey routine in UKeysHelper to test for invalid key presses when entering decimal numbers. Replaced duplicated code in FrPrintingPrefs and FrCodeGenPrefs with calls to IsValidDecimalNumberKey.

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

Merged delphi2010-port branch back into trunk.

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

Removed change logs.

Added svn:keywords property with Rev and Date keywords.
