hgweb: align entries in "changelog" and "revisions" pages of "spartan" style

Before this patch, each log entries in "changelog" and "revisions"
pages of "spartan" style are not aligned by column, because:

  - each log entries are separated "<table>" entries, and
  - there are no fixed "width" information for each "<th>"/"<td>" entries

This patch aligns entries in "changelog" and "revisions" pages of
"spartan" style by:

  - adding 'label' class to '<th>' for 'age' information, and
  - setting 'width' of '<th class="label">' with fixed size

'class="age"' is not used for this purpose, because it is also used to
set "bold" font-weight

"16em" seems to be wide enough to show date information fully, when
web browser disables (or doesn't support) javascript.
