HARET/P 1.1

After a long period of inactivity I'm releasing new HARET/P

Bugfixes:

• HARET/P is now a standalone prc (however StdioLib.prc is still required)
• vset now writes correct byteswapped data
• added command 'help'
• added command exec to run scripts form pdoc files. Beware! Due to the broken pdoc support in palmpascal you have to end your script with a newline
