Add Option to Ignore TextExpander Snippets

[hisaac]

@cstout1 reported that Plain Pasta strips styling from TextExpander snippets, and that they'd like the option to ignore those if possible.

I'm not sure if I will implement this feature yet, but I'm adding it here to remind myself that there's interest in the feature.

I've found today that with Plain Pasta enabled, you cannot cut/paste cells in Excel. It will instead copy/paste.

Thanks @cstout1. Think you could make a separate issue for that please so I can look into it?

[cstout1]

Ha! I had it written out as a separate issue and thought it was too similar. I'll trust my gut next time. Posting now.
