The build system should use FindLua51 to load the system lua if present

[worktycho]

Cmake provides a function FindLua51 to locate the system lua install if installed. We should use this function to find the system lua and use that instead of our own if installed. This should be bypassed when the CROSS_COMPILING flag is set so as to avoid dependencies on the build machine.

I'm not sure how that would work on Windows in MSVC - if there's no Lua project in the solution, then MCServer won't compile against any Lua.

It sets a variable to the path of the lua libraries. Cmake and MSVC both support linking in external libraries. we just have to import the system lua library as the lua target the cmake will sort out the MSVC project to handle it.

Bump because as of #1687 this will speed up travis builds.

I was thinking about opening a new bug, but then I found this open bug. I'd actually like to see the option to use system libraries for all of the dependencies if possible - maybe with a cmake commandline switch.
