WebAdmin: applied steffenp's patch which fixes a few syntax errors in Clearsilver template. Closes #4134.

TracQuery supports specifying lists of ids (fixes #4119)

The `ticket:` TracLinks has been extended so that one can specify lists (and even ranges) of tickets, e.g. `#12,23-34,35,36,50,40-42` (see #3011).

This works with the TicketQuery as well (#2604). However, in this context the tickets and ranges have to be separated by the "|" character, as the "," character is already used as an argument separator.

Example:
{{{
[[TicketQuery(group=type&id=12|23-36|40-42|50,format=table)]]
}}}

In addition, the "!" negation operator works also for such lists.

A few more fixes for compliance with [Genshi 421]

Make it possible to reuse the regexp string for ranges.

Some enhancements and bugfixes for the Ranges class contributed by Tim Hatch.

> ... I went ahead and added a `__str__` method that will return the most compact representation of the range so it could be used in links. It also has a few bugfixes:

* big-to-little ranges would throw an exception, but only if all were big-to-little
* certain overlapping pairs would cause weird internal representations which were nonoptimal
* a and b were not set for empty ranges, causing an !AttributeError on any `__contains__` call

Use the above to provide compact ranges representation for log: hrefs.

Ported [4233] to 0.10-stable (''related to #4128'')

minor cleanup for 0.10-stable: remove unused code

Make the wrapper for PySqlite cursor a bit more robust, and position some disabled ''print'' debug statements. Related to #4128.

Improve the ''Index by Title'' page.

Now, the !TitleIndex macro supports an additional ''group'' format, e.g.
{{{
[[TitleIndex(format=group)]]
}}}
which structures the output according to the common prefixes found in the Wiki page names.

Closes #1461.
