Handle stale PostgreSQL (or others) more gracefully. Closes #3394. Thanks to flfr at stibo.com for the patch.

Fixed log InterTrac links. This will only work when targeting a recent Trac (>= r3526) and the `<trac_prefix>.compat` configuration option is set to `false`.

InterTrac improvements: the InterTrac links are now able to take benefit from r3526, i.e. the corresponding URLs are of the form `/intertrac/<link>`.

However, as this will only work for Trac versions >= r3526, this is ''not'' yet the default behavior. This can be set on a case by case basis by setting the `<trac_prefix>.compat` configuration option to `false`.

E.g.

{{{
[intertrac]

# assuming t.e.o. is running r3526:
trac.title = Edgewall's Trac for Trac
trac.url = http://trac.edgewall.org
trac.compat = false

# the following Trac is 0.9.x
pysqlite.title = PySqlite's Trac (initd)
pysqlite.url = http://www.initd.org/tracker/pysqlite
pysqlite.compat = true
}}}

Move the \!InterTrac macro to the newly created intertrac.py file.

Add a generic dispatcher for InterTrac links, so that 0.10 Tracs will be compatible with the more generic InterTrac links created by subsequent Trac versions. Related to #3403.

Add " and ' to the list of characters that can follow a WikiPageName, and updated the unit tests. Fixes #3365.

Make sure we always store timestamps as integers.

jquery branch: Added jQuery script (1.0a, currently uncompressed). Initial changes to use jQuery in `trac.js`.

Start jQuery sandbox branch.

`from __future__` import needs to be at the top of the file (fixes #3351)
