Another improvement for the dustmite output match logic.

Dustmite: Force a match when a command failed, but the output regex matched.

Only force dustmite match when an explicit failing exit code was requested.

Fix matching linker/program results in dustmite mode and output match status messages.

Avoid copying compiler output files and copy *all* dependencies for "dub dustmite".

Avoid scanning for local packages for "dub dustmite --test-package".

Add a basic dustmite command.

Add support for execution result callbacks in the build generator.

Add Dub.overrideSearchPath to define a single and only path that is searched for packages.

When inferring the module name from the file path for "dub test", use the longest matching import path instead of the first match. ...

This fixes the inferred module name in case of multiple overlapping import paths.

Add unit tests for "==~branch" and changed the semantics of Version.isBranch. ...

Version.isBranch now also returns true for "~master".

Fix parsing of "==~branch" style dependency version specifiers.

Fix handling of remaining command line arguments (broken by previous commit).

Error out when excessive command line arguments starting with "-" are encountered.

Little doc clarification.

Use "%2B" to replace "+" in URLs when downloading packages. ...

This is not needed for code.dlang.org, but it's the correct approach in general.

Throw an exception when downloading using cURL fails.

Avoid using the deprecated canFind function.

Fix handling of targetType none packages and automatically treat packages with no source files as targetType none.

Fix triggering an enforcement for Version.INVALID.

Remove redundant dependency tree rebuilds.

Determine the version of the package in the root dir properly instead of assuming ~master.

Emit proper error message when trying to build a sourceLibrary.

Update README.

Fix the path-subpackage-ref example.

Change path based sub package definitions to use a string instead of an object entry.

Remove main file detection for library configurations and don't let <packname>/<packname>.d match as a main file anymore.

Make the warning message for non-existing locals more helpful.

Fix null pointer access for non-existent locally registered packages and output a warning.

Fix the check and error message for an existing DUB package in the selected root.
