fixes closing colorPicker when touching UI
Added new callback to customary position the colorPicker on toggle.
- minor optimizations
- added options ‘dark’ and ‘light’
- Multiple instances based on jQuery instances
- Backwards compatible (no changes in API)
- Options now have to be set on every instantiation.
- Option opacity is now toggled automatically.
Added method ‚toString‘ to colors.js; Converts color to HTML-string
with auto or forced alpha. Some minor optimizations.
