There should be Make compatibility

[vporton]

Compilation takes awful much time, among other reasons that to make it work, I need to recompile some modules several times.

To solve this I propose:

• Add a command line option to compile only a canister (and no dependent canisters).
• Add a command line option to deploy without recompiling.
• Add a command line option to output Make utility dependencies, which .mo files and which other canisters a canister depends on.

Then we can leverage the power of Make (including multithreaded compilations, by the way) to compile only what we need.
