(In [10141]) TracFormsPlugin: Rework changeset [9580], refs #6993.

Due to improper ticket handling the aforementioned report and suggested fix was gone largely unnoticed. Current code now resembles a slightly modified version of the patch. Thanks to andrewbates for the original contribution.

(In [10143]) TracFormsPlugin: Releasing version 0.3, pushing development to 0.4, closes #3445, #3550, #3741, #4759 and #8258, refs #3388 and #6993.

This is a major release requiring a Trac environment upgrade.

While the parser logic remains unchanged, there is a lot new supplementary funcionality to make TracForms behave more like the existing Trac core resources (ticket, wiki, attachment, ...).

This version performs a series of non-trivial db schema changes, that especially may leave traces of stale forms (i.e. recorded for wiki pages, that don't exist anymore). So please make sure to read the changelog, BACKUP your environment(s) before installing this version as usual and check the new db tables forms, forms_fields and forms_history after upgrading.
