This patch against revision 234 of the http://code.google.com/p/flot/ library
changes `$.plot.formatDate` to act more like the posix strftime() function. It
is slightly incompatible to proevious versions of flot. strftime() is the
behaviour most coders wit a Unix/C/Ruby/Python/Java Background expect. See
http://is.gd/9SpHy for an example of the common strftime() implementation.
Even PHP now generally like POSIX (http://is.gd/9Sqjf#) although the wildly
incompatible date function (http://is.gd/9Sqpl#) seems to be more popular.

I argue that flot should work like nearly all programming Languages with an
C/Unix heritage work. Also without this Patch it is impossible to generate
http://www.faqs.org/rfcs/rfc3339.html (ISO 8601) compliant timestamps. This
patch changes flot so that:

%d now works exactly like POSIX adding zero padding
%m now works exactly like POSIX adding zero padding
%e works like %d in previous versions of flot, but still differs from POSIX,
   since POSIX has  space padding.
%L workes like %m in previous versions of flot

This results in a slight incompatibility ot older flot versions. I suspect
that the impact is mininmal since, while now date formats without delimiters
are possible. Formats like YYYYMMDD are simply impossible without padding.
Impact on older code should be only of cosmetic nature.

Check an axample rendering with `xaxis: { mode: "time", timeformat: "%y-%m-%d" }`
at  http://static.23.nu/md/Pictures/ZZ71BDC910.png#. In an unpatched version
the first label would read 2007-1-1 instead of 2007-01-01 in the patched
version.
