[PATCH] Allow WikiFormatting in custom ticket fields of type textarea, and labels of any custom field.

[anthony.vito@…]

This patch builds on the patch provided in #925 and resolves the issue addressed in #1392 against the trunk. WikiFormatting of all custom field labels is allowed, and textarea fields can use as much WikiFormatting as they would like. Quite a bit of functionality for 7 lines of code ;) Of course I haven't tested this throughly. Since the preview for tickets is now done at the top with the full ticket display, you even get a preview of everything! This patch is against [1970] the trunk as of Timestamp
