Create ability to add presets

[MondayHopscotch]

It would be nice to be able to have effect presets in either of two forms:

1. A way to set default properties for a given effect. Ex: <preset wave height=30 speed=1.2>
   • After reading this in, all future uses of a plain <wave> will use height=30 and speed=1.2
2. A way to create a tag that applies a set of given effects when used. Ex: <preset dave_scared><shake size=4><smaller></preset>
   • After reading this in, user can use the <dave_scared> tag and anything within the tag will have the <shake size=4> and </smaller> tags applied

Notes: This can be done fairly easily by adding code for a CompoundEffect that just applies multiple effects in its own apply() function. A dev can then just register a new effect with a name for the full preset.
Doing it this way means code would have to be written for each new effect preset, whereas doing the parsing method allows non-coding individuals to create effects without assistance from development (other than, of course, the devs having to initially pass a 'preset' file into LucidText)
