Sketch Migration Notes
I tried to migrate to the non-MAS version of Sketch and had problems.
Steps I took:
1) I launched New Sketch. I entered my e-mail address. No e-mail received.
2) I launched MAS Sketch. It crashed at launch and told me the app was damaged.
3) Ok, no problem, I trashed the app and reinstalled from the MAS's purchases tab
4) Download appeared in /Applications. When MAS got to 100%, download disappeared. I've seen this before with MAS software.
5) I had to trash the new version of Sketch as well, *and* empty trash.
6) Re-download from the MAS.

all_strings.push(value.strip)
end
