Update README.md

I updated d-apt repository link.
Replace vibe install command by dub install because
Jordi's APT repository does't provide ``vibe`` package.
Updated DMD version.

Any way ``./setup-linux.sh`` doesn't work on Debian Wheezy:
Error:
```
Building configuration "application", build type debug
Running dmd (compile)...
Error: Executable file not found: 

Run 'dub help' for usage information.
```
Make allocators shared - due to D's GC this will cause bad memory bugs otherwise.

Specifically, the "nice" property of the GC to call finalizers in different threads than the constructor - even for thread-local objects - would cause an object to be deallocated by a different allocator than the one that allocated it.
Add an allowed_chars parameter to urlEncode().
Implement deregisterLogger().
Group the second overload of registerRestInterface under the same DOC comment.
fix the buggy function parseRFC822DateTimeString
Make MongoDatabase.runCommand public and improve doc comments. Fixes #261.
Make adjustMethodStyle UTF-aware and fix converting names starting with an acronym.
Add unit tests for parseRFC822DateTimeString and toRFC822DateTimeString.
Add static assertions to verify #line statements.
Fix removing wrong header

This commit fixes the incorrect removing of the Content-Encoding header. Instead the Content-Length must be removed. Now the responses are compressed, i.e. usually less data is transmitted.
Add reading encoded file from disk if present

This commit adds the ability to send pre compressed files if present
instead of compressing the file on each request.
Fix possible compilation error in HashMap.get by avoiding inout and add HashMap.clear.
Fix line number specifications.
Replace InvalidMemoryOperationError by a proper AssertError in HTTPClientResponse.~this. See #273.
Add overload UDPConnection.connect(NetworkAddress), UDPConnection.localAddress and TCPConnection.localAddress/remoteAddress properties.
Add property HTTPClientRequest.localAddress.
Fix the VibeDist client code for the latest version.
Only listen on loopback for VibeDist requests for now.
Implement missing methods/properties in the win32 driver.
