v0.1.4

• The Requirements section of both READMEs said rasuvaeff/understudy
^0.1 || ^0.2 || ^0.3 while composer.json has allowed ^0.4 since 0.1.3,
  and the usage examples already use 0.4 idioms.
• Allow rasuvaeff/understudy ^0.5. The core release narrows what a
  closing scope() verifies and refuses two impossible matcher
  configurations — both changes to the consumer's own test code, neither
  reaching this adapter, which needs no code change.
