Bump case-insensitive version
Merge pull request #33 from glguy/master

Bump case-insensitive version
Bump version number down to 0.9.3 (no reason to go to 0.10 now that we've decoupled snap version)
Relax case-insensitive bounds (didn't realize the lower bound got bumped so aggressively)
Un-bump snap-core dep (augh)
Reduce top-end snap-core dep.
