Fix test variable names.

Add test for #361.

Implement new optional dependency semantics. Fixes #361. ...

If no dub.selections.json file exists yet, optional dependencies will stay deselected by default, unless the "default" flag is set. If dub.selections.json exists, optional dependencies will only be used if present in that file, independently of their local installation state.

Add "default" flag to Dependency and fix "*" to match optional dependencies.

Extend DependencyResolver to properly handle optional dependencies.

Set FRONTEND variable for all GDC versions tested.

Output hierarchical log messages during dependency collection.

fix Issue #528 - fetch doesn't work for recently updated package ...

Revert "store metadata cache on disk"

This reverts commit 161aad0.

We only ask the package suppliers for metadata when upgrading or
searching a specific package version. In particular building an already
fetched package does not ask the package suppliers (only the package
manager responsible for locally installed packages).

In all cases where we get data from a package supplier we want to get
the latest available information. Therefor it doesn't make sense to
cache any metadata from the package suppliers on disk.

Not sure whether we still need the in memory metadata cache (e.g. for
multiple queries during dependency resolution).

Avoid possible range error.

Only use the first part of the Posix user info as name for "dub init". ...

On Linux, this is a comma separated list of fields, where the first field is the user's full name.

Fix class Dub's public default constructor.
