Use regex match to detect outlook 2007, 2010, 2013

Browse Source 
I encountered a variant of the outlook quotations with a space after the semicolon.

To prevent multiplying the number of rules, I implemented a regex match instead (I found how to here: https://stackoverflow.com/a/34093801/211204).

I documented all the different variants as cleanly as I could.
