Update build system

[jmjatlanta]

• The build system uses script files, which should (probably) be put into autotools format to aid in flexibility and portability. This will reduce compile times during development as only modified files will be recompiled.
• Many compile scripts contain references to bitcoin, zcash, and veruscoin. Give credit where due, but these remnants cause confusion.
• Should libraries installed by the package manager be used instead of downloading exact version to the depends directory? Should github submodule be used instead of wget/curl?

Notes about build.sh:
If defaults are used, should be the same as running the following from the komodo directory

autoreconf --install --force --warnings=all
./configure --disable-wallet
cd src/cc
./makecusom
cd ../..
make V=1

The above does not work, needs more research.
