Makefile: Test replacing spaces in the app name with a differen char

My idea is to use the no-space version of the app name in the Make
targets, and mv the files to the with-spaces version when everything is
built.

Decided to use the Unicode ZERO WIDTH NO-BREAK SPACE character U+FEFF as
the sentinel replacement character. We can always change it to something
else (like a string of unique characters) later if needed.

I took the Perl command from penguin359
