hgweb: code selection without line numbers in file source view

File code is presented as HTML ordered list, so that
line numbers are not selected with the code itself.

After this patch there is no ability to get a link to a line,
(however, they work). This will be added later.

This patch changes the visual appearance of the source a little:
- line numbers have dots after them
- line numbers don't have the stripey background
- 'line source' heading above the source lines removed
- line numbers and lines have a vertical line between them
  for better distinction
