* isAvailable(): check monotone's interface version and mark the interface as available if it matches (we might see later on if this alone is actually a good idea especially if we browse an empty database...)

Browse Source 
* _getCerts(): implement a cert cache and make multiple cert values easily available
* getCommit(), getCommitLarge(), getFile(), getPathInfo(), testHash(): implement
* getTags(): save the first found revision id for a tag as key in the associative array to make tags actually browsable
