CodeSnip Old Code (SVN)

* Changed to work on UTF8 strings instead of default ANSI strings.
* Updated comments about changes made to unit and added Rev and Date SVN keyword placeholders.

Prevented unwanted type conversions to default ANSI string in UUnicodeHelper unit's StringToASCIIString and StringToWindows1252String routines. Used some code from Stack Overflow (http://bit.ly/bAvtGd).

Removed unnecessary compiler directives.

Completed commenting of unit.

Commented unit.

* Added check for exceptions when decoding base 64 encoded checksum: we report a EWebServiceFailure exception.
* Corrected and modified some error messages.

* Removed unused IdException unit from uses clause.
* Modified some comments.

Removed uses clause from implementation section. Overlooked in r773.

* Reverted changes in r772 - needed IdGlobal unit in interface uses clause because it provides constant needed by conditional compilation directives.
* Reformatted some code.

Moved IdGlobal unit from interface to implementation section uses clause.
