Confirmation on license & two crate updates

[Cellesti]

Hi, i am trying to package Halloy for Alpine linux, and would like to confirm if the <project_license>GPL-3.0+</project_license> line in assets/halloy.appdata.xml means Halloy is licensed under GPL-3.0-or-later (as opposed to GPL-3.0-only).

It seems the short license identifier GPL-3.0 has been deprecated by SPDX.

Besides that, would it be possible to update these two crates in the next release:

• getrandom to 0.2.10 which fixes a problem with undefined reference to open64 that occurs on musl libc 1.2.4 that Alpine uses.
• half to 2.3.1 which fixes compilation on 32-bit x86.

Thank you.

@Cellesti Thanks for the report!

I've gone ahead and updated those deps, along w/ a cargo audit notification about openssl. 5241b87

I've also updated the SPDX identifier to GPL-3.0-or-later, which you can use. a24ddb5

Thanks again!
