Merge pull request #1207 from sbesson/homebrew_ice34

Refactor ICE_VERSION logic in the OMERO homebrew installation script
Check validity of parent object before creating link
Use parsed mimetype when uploading OriginalFile
Remove Homebrew/pip cleanup from the installation script

This cleanup step will be handled in the job directly most certainly using
`rm -rf /usr/local/*` to decrease the maintenance burden.
The TESTING_MODE variable only stipulates whether homebrew-alt PRs should be
merged for now.
