Use vars to hold target & profile in makefile_web

Browse Source 
I might sometimes build different profiles, so this gives me somewhere
to change them. It *does not work* for debug builds because of how cargo
works. So that sucks.

I can't think of a reason anyone would seriously want to change the
target, but I've made that a variable, too. WASM64 exists, but I can't
get a read on it's availability across browsers. The benefit seems to be
accessing >4GB of memory, which is not important for this project. Other
targets are for "desktop" platforms and so shouldn't be using the
makefile.
