#129 JavaScript validation is very slow for pubs with many titles

[Ahasuerus]

Now that Bug 694 has been fixed, edit forms allow up to 1,999 titles of the same type, i.e. regular titles, reviews or interviews. This is enforced in the JavaScript code, which only allows 1,999 titles per type. Allowing that many titles per type causes performance problems when submitting forms with a lot of titles. The JavaScript-based validation process takes a long time (over 20 seconds on a slow PC) and the submission creation process takes a long time. We need a different long-term solution.
