defines Module#qualified_const_(defined?|get|set) and String#deconstantize
This commit also implements a faster version of #demodulize I was unable
to isolate with git add --patch.
Not a big fan of the name #deconstantize. It complements #demodulize
getting rid of the rightmost constant, hence the name, but it is
unrelated to the well-known #constantize. So unsure. Could not come
with anything better, please feel free to rename.
