Option to build dependencies of the single package

[koudis]

As a developer/user, dependency manager I want to build a single package with all of its dependencies to simplify my workflow and speed up the integration of new packages.

When the package builds a single package by build-package --name <package_name> command dependencies are not built.
The user needs to build the dependency tree by hand - slow, not error prune etc.

The solution is to add the option "--with-dependencies" which when specified forces the packager to build the whole dependency tree of the specified package: build-package --name <package_name> --with-dependencies build all dependencies of the package in a same way as --all command.
