[LEDE-DEV] [PATCH] update triggerhappy package to version 0.5.0

[Daniel Engberg]

Hi Stefan,

Thanks for submitting a patch, I think however the preferred way is to 
use GitHub (PR) as that's the main repo and it's still under the OpenWrt 
project.

However, triggerhappy needs a bit more love than just adjusting what 
version to pull.

PKG_SOURCE should be changed to xz instead of gz, you can also remove 
the line completely if I'm not mistaken.
PKG_SOURCE_URL should use https instead of git because it "plays" better 
with firewalls and is the preferred protocol when pulling sources from 
git repos.
PKG_MIRROR_HASH needs to be added, which contains a SHA256 HASH of the 
packaged downloaded source code.

PKG_LICENSE should be GPL-3.0 not GPL-3.0+?

Best regards,
Daniel
