v1.3.0 update

v1.3.0 Changelog

Fixed:

•  filter settings was not saved
•  potential random values of track settings
•  potential crash when try to open file but there is no beat file

Changed:

• a track can be marked as "drum track" so the pitch stays as C4 and won't be affected by scale changes

Added:

• import MIDI file

MIDI import limitations:

• time division in header is "ticks per beat" only
• recommended shortest note is 1/16, if there are notes shorter than 1/16, the loader will increase BPM to try to accommodate that but may not be a good idea to have crazy fast BPM
• support only single pitch, not polyphony

MIDI files need to be put into the same folder as the beat files:

/Data/com.khors.pocketbm/beats
