Fixed "dub upgrade" when a package is stalled user or system wide.

Fixed copyFile() - was broken after replacing vibe.d's file handling with Phobos' "File".

Renamed all the "vibe" package to "vibecompat" to avoid conflicts.

Another round of replacing invalid uses of to!string(Path) with Path.toNativeString().

Added the dub-git arch package link.

Using pkg-config if available to build on Posix.

Updated README.md with new build instructions.

Compile fix for DMD <2.062.

Disabled curl peer verification and fixed writing of binary data to files. Works on Windows and OS X now.

Added support for building on Linux.

Added files necessary to build on Windows.

Fixed downloading of files.

Removed the vibe.d dependency by dragging in a minimal set of interfaces of vibe.d ...

The interfaces are reimplemented using standard Phobos functionality. Calls to
these interfaces will be gradually replaced by direct Phobos calls.

Added rudimentary support for the --arch= option and moved build type flag generation to a common place.

Mention the default command in the help screen.

Mentioning the registry + a list of key features.

Avoid use of deprecated functions + fixed package installation.

Fixed the system wide installation path on Posix.

By default, the compiler is not invoked directly (can be overridden using --rdmd).

Fixed up the VisualD and Mono-D generators and changed their names on the command line to lower-case.

Added a new "build" generator that directly invokes the compiler. ...

This generator supports all compilers in contrast to the rdmd based one and will later be the default.

Moved empty package creation from app.d to the Dub class.

Changed the initial project source code (dub init) to not depend on vibe.d.

"dub build" and "dub run" are now also executed using the generator system (RdmdGenerator).

Fixed linker and version flag translation for LDC

Added LDC support and improved compiler name maching (e.g. gdc-2.061 is now matched with gdc)

Also added support for gdmd and ldmd

Added basic GDC support (still has issues with the -of flag.

Implemented basic multi-compiler support (with only a dmd implementation right now).

Added a better error message in case dub was run outside of a package directory, issue #11.
