Merge new _touchList_vars with Chapstick
Merge _touchList_extends
Merge _touchLists from Chapstick

A couple of things are sticking out as being new/not necessarily
intuitive to me as I was looking at it:

- .touchList-menu
- .touchList-action
- .touchList-header

I bet these things can be simplified/eliminated in future versions.
Merge _touchForms

Couple of other strange things in here, as noted--mostly having
to do with excessively one-off patterns that will be hard to
override/control in the future.
Remove FS_textarea_factor

Since it was just set equal to 1, it wasn't doing anything in
math operations, and could be removed for clarity.
Remove $P_expander variable

Was some idiosyncratic value that ended up being equal to
half of $P_primary (aka $baseline on desktop Sq).
Remove $H_expanderClosed

Was just a multiple of LH_standard; seemed redundant to introduce
yet another variable.
Compile cleanly. Fixes #106.
