There was no 3.1 for some reason. The old sed-based path patching was
broken and resulted in syntax errors since it was a bit over-eager.
Instead of fixing it, I decided to replace it with a patch file which is
easier to inspect and will fail in a more obvious way next time.
The patch is now applied unconditionally, since it actually applies to
all linux platforms. The changes are localized to linux-specific code,
so it does not hurt to apply it on non-linux platforms as well.
Hedgewars needs a small fix to work with the new version. Done in the
same commit to avoid a broken commit.
* ultrastardx-beta: init at 1.3.5
* libbass, libbass_fx: init at 24
* ultrastar-creator: init at 2017-04-12
* buildSupport/plugins.nix: add diffPlugins
Helper function to compare expected plugin lists to the found plugins.
* ultrastar-manager: init at 2017-05-24
The plugins are built in their own derivations, speeding up (re-)compilation.
The `diffPlugins` function from `beets` is reused to test for changes in the
plugin list on updates.
* beets: switch to diffPlugins
The function is basically just extracted for better reusability.
