templatefilter: add support for 'long' to json()
When disabling the '#requires serve' check in test-hgwebdir.t and running it on
Windows, several 500 errors popped up when querying '?style=json', with the
following in the error log:
File "...\\mercurial\\templater.py", line 393, in runfilter
"keyword '%s'") % (filt.func_name, dt))
Abort: template filter 'json' is not compatible with keyword 'lastchange'
The swallowed exception at that point was:
File "...\\mercurial\\templatefilters.py", line 242, in json
raise TypeError('cannot encode type %s' % obj.__class__.__name__)
TypeError: cannot encode type long
This corresponds to 'lastchange' being populated by hgweb.common.get_stat(),
which uses os.stat().st_mtime. os.stat_float_times() is being disabled in util,
so the type for the times is 'long' on Windows, and 'int' on Linux.
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
