Python API

It uses a meta-language and a CSharpCodeProvider on startup. I will
release a tutorial on the forums soon showing how to use it.

This commit also adds an extremely basic loading screen which shows
while Desktop is getting everything ready. Which can take a while
if you have any Python mods. Thanks, IronPython.

+"""The io module provides the Python interfaces to stream handling. The
+builtin open function is defined in this module.
+
+At the top of the I/O hierarchy is the abstract base class IOBase. It
+defines the basic interface to a stream. Note, however, that there is no
+separation between reading and writing to streams; implementations are
+allowed to raise an IOError if they do not support a given operation.
+
+Extending IOBase is RawIOBase which deals simply with the reading and
+writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide
+an interface to OS files.
+
+BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its
+subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer
+streams that are readable, writable, and both respectively.
+BufferedRandom provides a buffered interface to random access
+streams. BytesIO is a simple stream of in-memory bytes.
+
+Another IOBase subclass, TextIOBase, deals with the encoding and decoding
+of streams into text. TextIOWrapper, which extends it, is a buffered text
+interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO
+is a in-memory stream for text.
+
+Argument names are not part of the specification, and only the arguments
+of open() are intended to be used as keyword arguments.
+
+data:
+
+DEFAULT_BUFFER_SIZE
+
+   An int containing the default buffer size used by the module's buffered
+   I/O classes. open() uses the file's blksize (as obtained by os.stat) if
+   possible.
