Leaflet library version 1.0-dev

Hi,
I just installed the Leaflet library from the beta1 version. It doesn't pass the regex. I also tried writing a "greedier" and less exacting regexp:

version[=:] *['"]([\d+\.]+)[-\w]*['"]

This works with several more numerals in the version string, and cuts away everything from the hyphen. Furthermore it is agnostic with regards to the usage of " or '. It was changed between versions, it seems (though I can't verify, since all the download links for leaflet are dead, except for the beta version).

My patch taking into account that the beta-version uses this format:
{version:'1.0-dev'}

Since the use of ' instead of " changed between versions the regexp is agnostic in this regard.

Darn, forgot to add leaflet to the beginning of the patch info :/

Applied and committed the "pattern" part of this patch.
Thanks czigor and pkej.

Available now in 7.x-1.x-dev and 7.x-1.2 and later when released.
