- added the possibility to have not one but a list of crawl start urls

Browse Source 
- the list of urls is entered in the expert crawl start in a textfield;
the one-line input field was replaced with a text box
- start urls can also be given in one single line where the urls are
separated by a '|'-character
- as an effect, the crawl profile cannot carry a single start url for
identificaton because it is possible to have more. Therefore the url was
removed from the crawl profile
- this affect all servlets which display a crawl profile: removed the
url field from all there servlets
- to work consistently with several start urls and the other crawl
starts which computed crawl start url lists from sitelists or sitemaps,
the crawl start servlet was restructured completely
- new rules for must-match patterns were created to make it possible
that site crawl starts also work with several crawl starts at once
