markers system

[tester]

Add as many markers as you wish (0-1 range), all draggable. Part of one of my projects, I develop.

There is still room for improvement, for example named markers, so that each marker is remembered individually with its tags.

Have fun!

update in first post.

tagging added. markers can have unique names now.

ruby hints mostly thanks to Nubeat7 and Trog.

Added some trigger optimizations.

And extensions. marker position can be defined as time (mins'secs.ms), considering that the window width equals time of loaded audio file.
