Fix missing LogicCommands

By removing FbTk/LogicCommands.o from LDADD in src/Makefile.am (commit
06655f6) I prevented the linker to pick up FbTk/LogicCommands.o and thus
rendered all logic-commands useless.

Using a small helper object to pull in the dependency fixes this problem
without relying on manually tweaking the build system.
