Improves and fixes demo example
Commits initial version of jsdoc for slider

Implements an API documentation generator specific to my
coding style (parsing event listeners and triggers). Very
early alpha stage, but better than nothing. Implement as a
local module for webmerge in a later stage (load via config).
Changes multievent lib to common coding style
[TASK] Commits merged release files
Improves jsdoc generator

Produces already quite an usable documentation, but the
code is really just hacked together.
