New Features

The default "bug commit" message will now include a summary of what changed (prefixed with the string "bug:", so you can still identify them in git rebase) (courtesy of @Komosa)
Added "bug create --generate-id" option to generate a stable identifier for new bugs

Golang Integrations

Implemented io.Reader, io.Writer, and io.Closer interfaces for bugs.Bug class. Reading or
writing a bug will read from or append to the Description of the bug.

Closing it will close the Read/Writer file descriptor, not close the bug.

This should make it possible to integrate bug into standard other Go programs by using ie. fmt.Fprintf
or anything else that takes an io.ReadWriter or an io.ReadCloser
Added a bugs.New("Bug Title") constructor that returns a bugs.Bug instance to make it
easier to use as a library

Fixed bug where help would not be printed if there was no issues directory
Added friendlier note suggesting creation of "issues" directory if it isn't present (courtesy of @Komosa, again).

The error message is still a little obtuse, but now at least has a hint of what's wrong.
Fixed bug that allowed you to create empty bug titles, if other options were present with bug create
Fixed a bug where "bug close" on multiple issues at the same time may have closed the wrong issue, if
the first issue caused subsequent directory indexes to change.

bug will no longer automatically try and invoke less for long output. This was causing problems on some platforms or for people who preferred other pagers.
Moved bug-serve (the HTTP implementation of accessing an issues/) directory to a different repo (http://github.com/driusan/bug-serve), so that it
can be developed and releases done independently of bug. It was never included in an official release
anyways.
