jivelite fork with meson/ninja build system

HI,

I'd like to advertise my Jivelite fork:

https://github.com/andreas-volz/jivelite

Tracis-CI: (config Ubuntu 20.04)
https://travis-ci.com/github/andreas-volz/jivelite

The biggest changes until now is introducing meson/ninja as build system. This fork builds with use of SDL/Lua dependency packages instead of the included ones.

See README.md for compile instructions and .travis.yml for Ubuntu maintainer packaging information.

Currently I develop JiveLite on Ubuntu 20.04 and let it run on my RaspberryPiOS system. Before I had piCorePlayer as base, but had higher requirements for my prototype.

So I would request for feedback based for my modifications. Maybe you could compile it with your favorite distributions and report your experience.

if you're a Windows or MacOS user/developer you might help me to add meson support for those operating systems. I'll accept patches.

I didn't try yet to compile the meson fork with piCorePlayer and native SDL/Lua packages. But this is on my todo list.

My other Jiveluite change planes are regarding two different new Applet ideas and maybe support for SDL2. But depends on time and future interest.

regards
Andreas
