RegexRails

• Can now use lecturns in place of signs.

  Lecturns work the same as signs, but only takes the input from the current page.

• Add not (!) operator to equals and contains.

• Add rename cart command

• Use original sign value in regex mode.

Previously, the sign would compare stuff case insensitive. Now it only does that on equals and contains.

• Minecarts don't cost anything to rename in an anvil now.
• Remove console log spam.
