jQuery dependency for Trac 0.11 should be < 1.3

[anatoly techtonik <techtonik@gmail.com>]

Hello,

Trac 0.11 ships with jQuery 1.2.6
However, Debian patches remove this file in favor of libjs-jquery
package which contains version 1.3.x
This breaks plugins for Trac 0.11 that rely on 1.2.x jQuery features
removed in 1.3.x

How to properly add dependency for jQuery<1.3 to trac package?

Thanks.
