v0.4.0

Fix

• Renames orginalSrcAttribute option to originalSrcAttribute. The misspelled orginalSrcAttribute can still be used and will override originalSrcAttribute if both are set.
• Optimization, preloads images in single loop.

Feature

• Adds focus and blur listeners, matching the mouseover and mouseout listeners, respectively.

Chore

• Bumps various dev / build dependencies.
