games/cockatrice: Add server component

[sbruno]

Summary

I've attempted to add the server component such that the
game can be installed with/without the server and that the server
can be installed with/without the required mysql server backend.

games/cockatrice/Makefile

too long

20–21

USES should happen earlier. See Order of Variables in Port Makefiles.

29

Use OPTIONS_SUB instead.

30–32

Use options helpers.

[sbruno]

Switch top options helper and OPTIONS_SUB where possible. I still
am not clear on how to make USE_QT5 do the right thing in this
framework.

[sbruno]

I can't seem to get USE_QT5 to do anything with the OPTIONS_SUB framework. Does it work?

SERVATRICE_USE=    qt5+="sql sql-mysql websockets"

Hrm. I don't think I have the right syntax. I keep getting QT5 failures:

[sbruno]

I guess this is the proper way to do OPTIONS_SUB here. I dunno.

It doesn't look like OPTIONS_SUB support "qt5+="

[sbruno]

Use the proper syntax for USE_QT5= for the global QT5 requires.

Use the proper syntax for OPTIONS_USE= qt5="" so that different
options pull in their required deps. (thanks mat).
