tigefa4u projects Trac

Simple refactoring to split up and explain the current WikiPageNames regexp

InterTrac adds [ticket:40 InterWiki] support. However, for now, !InterWiki prefixes which are themselves WikiPageNames are only working when enclosed in square brackets (e.g. {{{[MeatBall:InterWiki The MeatBall InterWiki page]}}}).

Added `...` syntax in addition to !{{{...}}} for marking up inlined code

Shorthand InterTrac links implemented (e.g. {{{#T234}}} and {{{[T1899]}}})

Detect and reject changes to tickets that have been modified since the user started editing. Closes #1228

Remote InterTrac links implemented

Implemented InterTrac links for sibling environments (tracd only currently). This required moving the storage of rules and related informations, such as external handlers and link resolvers, from the Formatter class to the !WikiSystem class. This last change should also contribute to fix #1750.

Fixing minor annoyance with SVN 1.2 unit tests, on Windows

InterTrac: small refactoring of {{{lhref}}} and {{{shref}}}. Also added patch #1751.

Fix {{{send_file}}} implementation in mod_python front-end so that {{{RequestDone}}} is raised also for 304 responses.
