Thanks! Now at long last belatedly merged.

@mezrin, as we're looking to resurrect the project by expanding the set of maintainers for it, I've also added push access for you. Feel free to directly commit improvements in case you're still using the library.

As a minor point, if you still recall, what was your rationale for changing the null checks in sendfrom()/sendmany(): e07971b

As I remember I had to deal with the wallet that has account with the name '0'. I.e. numeric zero. Old code throws exception for that case. (Maybe not '0', but some name that did not pass the checks).

Generally Bitcoin allows to use any string as the account name. Therefore the only correct check is 'is_null'.
(Take into account auto-conversion of types in PHP...)

@mezrin Thanks for the explanation, makes sense. PHP's weakly-typed empty() checks indeed would include zero values and "0" strings, so makes sense to narrow it down.
