Time to get 4.13.0 out. Here is the first release candidate.

There have been quite a few changes since the alpha. The most notable are:
 * Added support for file signatures in security.ima xattr
 * Finalized syntax for rich dependencies
 * Enable {} expansion in rpmGlob()/%files and enhanced glob handling

But there are also smaller changes and fixes:
 * Fix compressed patches
 * Don't warn when an escaped macro is in comment.
 * Add --filetriggers query option
 * Fix for Py3 compatibility
 * Do not bytecompile python scripts in docdir
 * Improvements to find-lang.sh and perl dependency generator
 * Use default value (currently 7) for XZ compression
