add system for (To keyword, ...) reminder text (#69)

-added handle_action_rt(to:"name", "Action") to be used in keyword code. It will return either "To name, action" or "Action" depending on if the reminder text is removed from the keyword.
Example: {handle_action_rt(to:"populate", "Create")} a token that's a copy of a creature token you control.
-added handle_merged_rt("Normal", moved:"Alternate") to be used in keyword code. It will typically return "Normal", but will return "Alternate" if its keyword gets moved.
Example: {handle_merged_rt(if param1.value == "ns" then "They’re artifacts" else "It’s an artifact", moved:"A Food token is an artifact")} with "2, T, Sacrifice this artifact: You gain 3 life."

 • Added support for Custom Watermarks up to a maximum size of 1024x1024. Watermarks that aren't 500x500 will still need to include their height and width.
 • Split the "blend with colors" watermark option into one that applies to custom watermarks and one that applies to default watermarks.
 • Reorganized the Set tab into something hopefully easier to navigate.
+• Added the keyword utility handle_action_rt(to:"name", "Action"). This can be used to add "To {name}," before the reminder text when it isn't right next to the keyword, such as handle_action_rt(to:"forage", "Exile"). capitalization matters here.
+• Added the keyword utility handle_merged_rt("Normal", moved:"Alternate"). This can be used to add clarifying text when reminder text is merged, like in [card]Cache Grab[/card]. Unlike the previous, this only changes during reminder text merges, not any distance from the keyword.
 • Added the up and down triangles as mainframe transform options.
 • Added support for dungeons with 8 levels.
 • Added option to remove backface rarity symbol to Mainframe DFC.
