Replace makd with dub and upgrade deps

[mihails-strasuns]

Major build system rework:

• each generated binary defined as separate DUB sub-package
• each top-level utlity library package is also defined as DUB sub-package
• tests redefined using dub configurations
• dependency versions upgraded to latest available (i.e. vibe.d 0.8)
• makd only used for packaging
• Travis script updated to match our current standards

This is one huge commit but all these changes are so subtly related that I really don't want to spend time trying to untangle this :(

I think if we move forward in this direction eventually we could even create a MakDub.mak file in makd to use the same conventions as in Makd.mak but with these adaptions to dub.

I think that at the very least there is a solid case to split packaging related bits of makd into own MakPkg.mak so that it can be used in any project (even non-D) without any other MakD conventions coming into effect.

Updated:

• split into several commits (low hanging fruits)
• more generalized makefile definition
• dub -q calls (quite, warnings/errors only) to make travis log more readable

I checked out the branch and tried make test with the following result:

make test won't work because of current limitations in makd (I can't disable all automatic targets it implies). Because of that new make dub-test was added for CI purpose.

Thanks!
