Fix snap build errors

@raymix in most of your helper functions you are using exitWith {}; in
the same way the main player_build uses it. The problem is exitWith
inside of a called function only exits that function, not the parent
script it was called from.

When a helper function exits the main script continues on with undefined
variables and other problems. The easiest solution was to just remove
these helper functions for now. I just directly substituted their code
back into the main modular_build file and removed the passes to and from
them.

We should consolidate player_build and modular_build into one file first
since they are about 80% identical. After that we need to integrate
plot4life. Dividing player_build up into smaller sub functions like this
can be left for last.

I tested this thoroughly and can confirm the undefined errors are fixed
now.
