Advanced graphics options

[luxaritas]

Namely enabling/disabling graphical embellishments (basically the stuff that low perf mode handles now, but fine-grained for personal preference). This might include:

• [ ] Bubbles
• [ ] Background gradient
• [ ] Pair markers
• [ ] Strand directional markers
• [ ] Nucleotide animation (ie, how they always move back and forth )
• [ ] Antialiasing
• [ ] Molecule binding sight animation
• [ ] "Great pairing" notification

Edited to add checkboxes and add a couple options
