Use the exact dependencies instead of base packages for missing dependency resolution. Fixes #140.

Move dub.utils to dub.internal.utils and update copyright dates.

For the DependencyGraph, when dependencies are looked up, provide the base package name, to the callback.

The dependency in terms of the DependencyGraph is the base package and not the sub package. ...

Only enqueue one update action for the same package.

Added some very basic unittests for the DependencyGraph

Fixing unittests

Fix error message for unknown sub-packages. See also #87.

Refactor code. ...

Moved and renamed RegistryPS to dub.packagesupplier, made Dependency a struct and improved code convention adherence.

Rename log levels to be in line with the latest vibe.d versions.

using size_t to compare parts of the version string

dub's Version are now based upon Semantic Verioning 2.0.0-rc.2.

Do not enforce the components to be valid, when constructing a Depenency object from another. The Dependency will then return valid() = false, which is in fact a valid state of the object.

Add exception messages.

Fixing issues in getTopologicalPackageList and getPackageConfigs because of added "optional" flag for Dependencies.

Package updating could work with optional dependencies.

Added "optional" dependency flag.

Move all source files outside of "dub" to "dub/internal".

TODO "optimize": Done ...

Suffix checking easier and more efficient.

I also fixed some unittests some others that triggered I disabled (Soenke please review).

The internal package representation is now JSON agnostic + streamlined configuration and dependency handling. ...

Still missing for the new configuration handling:
 - A way to select which configuration to use for a dependency (instead of the default "library")
 - New method to define a default configuration per platform and mode (application/library)

stashpopcommit

Replaced try-catch in unit tests with assert(Not)Thrown().

Fixes comparing Version objects pointing to the same branch.

Version and Dependency support branches, added unittests.

Renamed all the "vibe" package to "vibecompat" to avoid conflicts.

Fixed "==" version comparisons - were not handled at all.

Added support for local package definitions in package dependencies and fixed recursive dependencies.

Implement basic support for user/system installed packages and local packages. ...

Also removed a lot of (caught) exceptions. The installation/uninstallation code was moved and modified to the new package manager, which is now responsible for all locally installed packages.

Fixed an invalid enforcement.

64-bit compile fix.

Fixed upgrading/install logging of ~master dependencies.
