µBlock 0.3.1.2

Changes:

• New language available:
  • Spanish, by contributor Conor Anderson at Crowdin
• Performance (marginal): no need for mutation observer if no scripting on the page

Fixed but not closed:

• uBlock's third-party filter option does not follow strictly ABP's semantic
  • Code is commented out
  • Waiting for cases to show up to justify adhering exactly to ABP's semantic of 1st-/3rd-party

Closed as fixed:

• Need exception for Avianca e-checkin and possible others
