Generate an issue template for bug reporting

[izgzhen]

For each failed build, it would be convenient to generate a link to create an issue on github (https://github.com/snowleopard/hadrian/issues/new?title=foo&body=bar). The platform, git hash etc. can be easily composed in bash.

P.S. In fact it is very similar to what Hadrian's brick is doing, except that benchmark-related data is not useful in this case.

@izgzhen Thanks, indeed, that would be very useful!

P.S.: It's a good issue for a newcomer -- please volunteer and send a PR.

I suggest a info.txt or similar and telling the user to upload it by hand.

Hadrian has been merged, and all new issues are to be submitted on Trac #705.

I think we can close this.
