Often it is very useful to have flash/status messages of several
different types, for example to be able to differentiate between
informational messages, warnings and errors. To do that I made
a simple extension to WebHelpers to add category support to its
Flash class. The change is completely backwards compatible, so if
you do not need categories you will never notice them.
Patch attached.
Wichert.
