This moves the space inside the line anchor and makes it non-selectable, so that when copy-pasting, only the content of line lines is actually copied. At the moment, this seems to behave slightly incorrectly in firefox which inserts a double line break due to the presence of unselectable elements inside the selection. Hopefully it will be fixed, chromium behaves fine. It also still works decently on text-browsers. ok stsp@

The page querystring parameter is long gone and currently unused. It was replaced mith the "more" buttons in all the views, except INDEX that uses `index_page'. ok jamsek

Breadcumbs are useful not only in the TREE and BLOB action, but also in COMMITS/BRIEFS and BLOB. prodded by stsp@

While here pad line numbers with spaces instead of zeroes to match the blob view.
