#1 Execution of standard form after 'SERVER_ERROR'

[jochentb]

This patch enables the execution of the standard form
mechanisms after a status 'SERVER_ERROR' or 'SUCCESS'
encountered. This functionality has not been
implemented yet.

Some minor changes:
- Only prepend '&' as argument separator after the
first argument has been processed. The first argument
might not be the first element in the elements list.

- Sending image submit coordinates: Changed order how
argument separator '&' is added and added check if not
the first argument.

- Changing "dataStr += (thisInput.name ..." to "dataStr
+= (controlName ..." when handling the <select> options.

Found incompatibility:
This script is not compatible with IE 5.5/Win as
mentioned on the home page because
getElementsByTagName('*') was first introduced in IE 6.0

Tested with:
Firefox 1.5
IE 6.0
Mozilla 1.6 and 1.4
Netscape 7.1
