[PATCH 5/5]: cleaning the template parent management in hgweb

[Goffredo Baroncelli]

Hi,

the template pages contain two entry named #parent1# and #parent2#; this is no good
because with the template system implemented in hgweb both the functions 
can be replaced with only one entry named "#parent#".
The code in hgweb will replace this tag with the appropriate number of parents ( one, two...
or more if and when will be used ).

The first two patch perform this change in two step: 
1) change the code to manage only one entry ( #parent1# )
2) remove any reference to #parent2#, and change both the code and the templates to
   rename #parent1# in #parent2#

the last three patchs are clean-up.

The patch are five

- patch #5
remove the unused function hgweb.parent()
