fix #1556: dub --cache=local fetch + build ...

Building a package that was locally cached failed, because
the dependencies whould be fetched at the wrong destination.

For example if one tries to build the package 'optional':

$ dub --cache=local fetch optional
-> optional is now at ./.dub/package/optional
$ dub --cache=local build optional
-> fails because the dependency bolts was fetched to
./.dub/package/optional/.dub/package/bolts.

This is fixed by not overwriting the root path if dub builds
a package from the cache.

fix #1891: documentation of dub fetch

Fix issue 1277: Missing dub.json causes infinite loop ...

For some reason, having a 'source/app.d' was recognized as being in a package.
This would load an empty package with no manifest and send the dependency resolver
in an infinite loop.
Remove the special detection of 'source/app.d' and rely only on manifest.
Another option would have been to detect 'source/app.d' as a single-file package,
but that is a bit too much magic (the user can just 'dub run --single source/app.d').

Add flag --submodules to add git submodules in the project folder as available packages.

- Also cleans sub packages
- Does not exit on first error anymore, but continues with the next package

Add flag --submodules to add git submodules in the project folder as available packages. ...

Adjust git version determination to support submodule folders

Command dub lint added

Support fetch sub-package

fix #1691 - dub build :sub-pkg broken ...

- fixed by skipping auto-fetch for abbreviated local subpackage name

add non-interactive mode to build command ...

- useful to build already fetched package
- skips online search and interactive fetch dialog

improve output in case package was not found ...

- also quote package name to avoid confusion with certain names

tabify code added with #1428 ...

Merge pull request #1662 from kubo39/kubo39-patch-1 ...

Remove `dub list-installed` command

Custom init type (#1658)

Remove `dub list-installed` command

dub run <package> should search the registry on failure

Add dub fetch <package>:<version> shortcut

code consistency for add command ...

- factor out common code to add dependency
- also support <package>=<version-specifier> depspecs in dub's
  interactive init
- more specific handling of exceptions around querying registry
- abort dub add when querying latest version fails
- replace self-written (and incomplete) recipe finder and loader
  with existing loadCwdPackage and use package's rawRecipe

support version specifications in new add command ...

- Also simplify test to just grep for addition, fetching and building
  dependencies is already tested elsewhere.

improve package supplier fallback logic ...

- scope (failure) did swallow fatal errors
- improve logging of failures and successes
- rethrow failure of default registry instead of from the last one
- remove failing package suppliers, so we don't keep beating dead horses

Note that some retry logic is already done interally by package suppliers,
so a failing one is unlikely to recover on the next usage.

Revert "enable feature by default for testing" ...

This reverts commit 25e0387.

- also explicity add flag for dub describe test
