Improved handling of generated files

Place a pre-built copy of generated source files in src/built/, so that
users building SolveSpace from Git without the tools or setup necessary to
generate these can still complete the process.

Makefile.msvc: Use slashes consistently, and added rules to copy files from
src/built/ if needed

configure.ac: Check for presence of src/built/ at configure time

src/Makefile.am: Handle the generated *.table.h files together with
icon*.h; updated the source-generation rules so that the files are created
in builddir, not srcdir; added rules to copy files from src/built/ if
needed
