Managix v1.2

Welcome to v1.2 of Managix!

Added an important feature:

[ADDED] In ManagixDefaultAsyncSaveJobs, "buffersMultiple" now has a new callback: afterSave, which is executed after saving the buffers.
Similar to the existing ManagixDefaultAsyncLoadJobs -> buffersMultiple, which has afterLoad callback.

Thanks for listening :D
