Rename "Lock layer to" to "Lock to layer" to harmonize with other names

[parke]

Chrysalis has the following bindings:

Shift to layer Move to layer

However, the lock binding is named differently:

Lock layer to

My suggestion is to rename the Lock to be:

Lock to layer

This will harmonize the names of all three binding types.

Note that the current inharmonious names are probably a result of the underling C function names:

LockLayer(n) MoveToLayer(n) ShiftToLayer(n)
