Rename Init() to Open() as we need this method to return bool to indicate its success in order to avoid using non-initialized handle later. Init() is also reserved, by convention, for the common part of all class ctors in wx code. Remove m_initialized entirely, it doesn't seem to be obviously better to cache the failure to create a session than to retry doing it every time (in fact, it would seem to be worse) and not having it is simpler. This commit is best viewed ignoring white space.
