Turn off/hide any patterns that aren't working

[cswales]

Patterns are getting picked up from the jar files rather than from the patterns list, which means that some patterns that compile, but do not work (such as ShrubRiver) are showing up in the UI.

Need to add @LXComponent.Hidden to them to keep them from showing up.

These include:
AutographedPattern (base class, should never show up)
SpiralArms
WavesToMainTree
PartyRings
ScrambleEffect
Brightness (used, just not as a UI selectable class)
Snowflakes
Stringy
Fountain

There may be more that aren't working properly

AutographedPattern (base class, should never show up)

FYI - better solution for these is to just declare that class abstract - LX will notice that it's abstract and won't show it in the UI, and even better Java won't let you even try to directly instantiate it.

For the rest @LXComponent.Hidden ought to work just fine.
