Add custom Matrix Python SDK. Solves #5 and #2

This commit releases a custom Matrix Python SDK. This means that the
most important classes---MatrixClient, Room, and MatrixHttpApi---are
inherited by Custom classes. This enables us to change behaviour or add
new features in a well structured and predictable way.

The first issue that is solved with this new custom SDK is the problem
that was introduced in #2.
