version 3.6.0

What's new:

Added:

• alphaBars effect, which is similar to lumiBars but preserves bars' amplitudes and also works on discrete frequencies mode and radial visualization;
• outlineBars effect, which extends the usage of lineWidth and fillAlpha to octave bands modes;
• isAlphaBars and isOutlineBars read-only properties.

Changed:

• showLeds and isLedDisplay have been deprecated in favor of ledBars and isLedBars, for consistent naming of effects.

Fixed:

• getEnergy() would not accept a fractionary initial frequency.

Improved:

• Regenerate the current gradient if/when it is re-registered (#21);
• The fluid demo now shows the status of read-only flags, for better visualization of interactions between different properties.
