CodeSnip Old Code (SVN)

* Moved IsHexDigit routine from UUnicodeHelper unit to UUtils.
* Removed from UUnicodeHelper unit all character test and case conversion routines that mapped directly onto methods of TCharacter or to CharInSet in SysUtils unit.
* Modified units that used these routines to use replacements in Characters, SysUtils and UUtils units.

Removed {$WARN SYMBOL_PLATFORM OFF} compiler directives: these warnings now switched off globally.

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

Fixed a potential bug in UUtils.StringToStream.

Merged delphi2010-port branch back into trunk.

Fixed potential GetTickCount wrap-round bug in Pause routine in UUtils unit.

Removed compiler directives that switch off "unsafe" code, type and cast warnings. These warnings are now disabled globally for the whole project.

* Removed PathToDir and DirToPath routines. Code must now use ExcludeTrailingPathDelimiter and IncludeTrailingPathDelimiter from SysUtils in place of these routines.
* Made changes to other routines that used one or more of the deleted routines.

Modified UUtils.pas unit's DateStamp explanatory comments and date pattern string to refer to fact that the routine's output is as defined in RFC1123.

* Removed SpecialFolderPath and TempFolder routines from interface of UUtils.pas - no longer used since TSystemFolders class now has comparable methods.
* Removed redundant helper routines FreePIDL and PIDLToFolderPath from implementation section of unit.
