Front end bugs

[sleitner]

Given an example query there are a few small pagination-related bugs.

1. Greyed out buttons are still clickable
2. Clicking Prev can produce a server error
3. Setting a limit > 100 only displays 100 records per page

• The pagination at the bottom is calculated based on the actual limit, not 100. If we decide 100 should be the cap for html, we need to update pagination accordingly.

I'll do this.
