BDOG-2077 Modify list.js source code to allow search by punctuation

This bug was introduced in List.js:2.3.0, and a fix has been proposed
which has not yet been merged: javve/list.js#721

This commit uses the proposed fix above.

Futher detail:
Prior to v2.3.0, the search used regexp, so special chars had to be escaped.
However version 2.3.0 implemented a new, faster search which didn't use regexp.
Therefore by continuing to escape special chars, it's not possible to search for them.
This defunct 'replace' function should be removed
