Query git to determine the current DUB version and report it on the help screen. Fixes #39.

Fix dangling else warning.

Add support for DUBPATH and "add-path" + change the default installation location to the DUB user path. Fixes #64. ...

This change allows to specify a number of directories in addition to the system and user DUB package directories to search for local packages.

Full list of changes:

 - Add support for the DUBPATH environment variable (a (semi-)colon separated list of paths)
 - Add support for "dub add-path" and "dub remove-path" to add static search paths
 - The branch of local packages with no "version" field in their package.json is now inferred using "git rev-parse"
 - The structure of the user/system package directories is changed from "packages/<packname>/<packver>" to "packages/<packname>-<packver>"
 - There is no project local package directory (".dub/packages") anymore - packages are instead installed to the user package directory by default
 - Upgrading and uninstallation is partially broken in this commit - will be fixed later

Add exception messages.

Compile fix for -inline compilation.

Add unit tests to the path module and make \\UNC\ paths absolute.

Remove all unit tests from the processcompat module as many of them failed (not an issue since the new std.process is now in DMD 2.063).

Deprecate "relaxProperties", remove the default -property switch and warn about using them. Fixes #73.

Fix warnings for latest DMD beta.

fixes unc path error

Fix object directory for -op switch in the VisualD generator and prepare for different project file directories. ...

Future versions may choose to put the project files in the .dub directory (the solution file will still stay in the project's root directory).

Change the file dictionary to a file list for "dub describe"'s output.

Implement a first version of "dub describe".

Improve JSON pretty printing and appending.

Log warnings/errors/diagnostics to stderr instead of stdout.

Implement the "noDefaultFlags" build requirement. Fixes #68.

Write the "optional" field out as bool instead of string.

Add build workaround also for LDC.

Add warning for package names with upper case letters, but handle them gracefully.

Preparing for the new std.process in Phobos.

Attempt to replace the Ubuntu fix by a more generic fix that does not depend on a distribution name. See also #71.

Silence lsb_release output.

Syntax error fix.

Redo build script to directly call the compiler + limited compiler auto-detection. ...

No rdmd is necessary anymore and the call to "uname -a" has been changed to
"lsb_release -i" to detect the distribution more reliably. This needs to be
properly fixed, though, by looking at the GCC version or by using a
workaround that works on older _and_ newer versions.

Fix LDC linker flag specification and add workaround for conflicting object file names.

Use separate compile/link only for dmd (and not for ldmd and gdmd).

Use -d-debug instead of -debug for LDC.

Fix compilation with latest LDC.
