Search pagination

Search results are now shown on different pages. Approximate size of
results shown. Search results can be sorted. 

Strict search with "" marks also available. 

All users can search all text. Don't know how to change this.

SearchServlet may be unneccesary.

Future plans: better input handling, more CSS, pages with numbers.

Bugs: Only one word of query is shown in search box. ÕÜÖÄ are not shown
as characters. Unexpected query size and limit make the HTML act weird.
