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)

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.

Compiles using latest vibe.d and DMD 2.061.

Initial commit (more or less the same code as used for vibe.d's vpm).
