v0.7.2

Improvements:

• Images (and animations) are now cached at $XDG_CACHE_HOME #65
• We now have man-pages! They must be installed manually in your system by moving the files in doc/generated to the appropriate location. Typically, you can figure out where that is by running manpath. The script doc/gen.sh will create the above directory and all the relevant manpages. Note that the script depends on scdoc being installed in the system. Have a look at it for more details.
• We now also have automated spell checking. This let us fix a number in typos in our documentation, both internal and user-oriented.
• New option for swww-img: --sync. This syncs the animations in all your monitors. Note that all monitors must be displaying animations in order for it to work.

Internal:

• Integration tests are not run by default. You must now use cargo test -- --ignored to run them. This will make it possible for some
  people (like the ones trying to package swww at Nix) to run some of the tests in a sandboxed environment where they don't have access to the wayland server. If anyone is interested in running all tests, they can do that with cargo test -- --include-ignored.

I will start being very busy very soon, so I will probably only have time to publish minor bug fixes and/or update the dependencies for a while. Expect to wait a long-ish time until the next release, unless there's some awful bug in this release I failed to notice.
