Remove redundant blank line

[ci skip]
Compile after testing

Should fix Emacs snapshot tests on Travis CI
Add missing :package-version keyword
Generalize status reporting

Add flycheck-status-changed-functions to hook into all status changes of
Flycheck.
Make mode line format customizable

Do not assign flycheck-mode-line anymore.  Instead, use a standard mode
line template and let the mode line assemble the final result.

This makes the mode line format entirely customizable, and lets users
chose their very own means of reporting the Flycheck status.
Show stack traces when loading Flycheck fails

Do not navigate our own list of error locations, but instead scan for
changes to overlay properties, which is more efficient, and always in
line with what the user actually sees in the buffer.
