Fixed issue with running imager on system with spaces in path

Was running into errors when using Craft with Imager and MAMP on Mac. Problem was spaces in the disk and directory names. fixed this with encapsulating file path in double quotes.

Before:
`/usr/local/bin/jpegoptim -s /Volumes/Drive Name/Website Project/public_assets_html/imgcache/327a39dbf78c825648a75687f040efcf.jpg`

After:
`/usr/local/bin/jpegoptim -s "/Volumes/Drive Name/Website Project/public_assets_html/imgcache/327a39dbf78c825648a75687f040efcf.jpg"`

Also added logging of the command for troubleshooting.
