templates: rename `Last change' column in hgwebdir repository list.
This patch changes column headers in the templates that previously
said `Last change' to `Last modified'. Neither code nor functionality
are changed other than that.
For some time now, I have been annoyed by the fact the `Last change'
column didn't list the age of the youngest changeset in the
repository, or at least tip. It just occurred to me that this is
because the wording is slightly misleading; what the column in fact
lists is when the repository was last *modified*, that is, when
changesets was last added or removed from it.
The word `change' can be understood as referring to the changeset
itself. Using `changed' would be ever so slightly less
amigous. However, the standard nomenclature in this case is
`modification date' and `Last modified', which is incidentally entirely
unambigous. Hence, `Last modified' is the wording used.
