Generate MD5 / SHA1 checksums for browscap files

[asgrim]

I wish to automate the updating of the browscap.ini files on our production servers, but I can't determine a way to programmatically verify the integrity of the downloaded files. Can you please also generate checksums that are hosted alongside the browscaps with predictable URLs so that we can automate verification of file integrity?

[09:07:16] <browscap-user> Please add on browscap.org next to the link to the files link to their md5.

[09:07:55] <browscap-user> Often the files are not completely downloaded and the failure occurs
