browser/navigate: _find_nextprev allow for space sep rel attribs

Browse Source 
The _find_nextprev function of browser/navigate.py only checks to see if
the rell attribute equals 'prev', 'previous', or 'next'. This patch
changes this to check for a set intersection between {'prev',
'previous'} or {'next'} and the set of the space separated list of the
rel attribute.
