New stuff!

- Fixed another thing with desync between audio and visual

- Hi-Hat choking - when open and closed hat are placed on the same beat, the open hat is ignored and closed one is played on two channels as shorter note

- You can now hold mouse down to paint pattern

- Clicking on instrument label besides changing some instruments should also play a sound

- Fixed cymbal spelling

- Added clear and delete pattern buttons in "Create" mode

- Ability to paste text (CTRL+V) representation in "Create" mode, it doesn't have to be the full list of instruments, but the pasted pattern should have 16 beats, here is the example:

CH X-X-X-XXX-XXX-XX

SD ---X-XX-----XXX-

BD XX------XX------

AC X-XX--X-X-X-X-X-
