Don't push/pull .sass-cache

I thought for sure this had been resolved in a previous version, and that there was a thread on here about it, but nothing turned up in a search.

.sass-cache can probably safely be excluded by default, but it would be helpful to be able to customize this, too. (I tried adding it to File Exclusion Filter in Exporting preferences, but it doesn’t work.)

YES, I collected all of these here, please vote up Option to specify ignored files in MagicSync
