safari paste bugfix breaks MS Edge (DataTransfer.types is not Array)

[metamatt]

When pasting into trix running in MS Edge (14 or 15), we get: TypeError: Object doesn't support property or method 'some'

This seems to be because code introduced in 95db10b (release 0.10.2) assumes paste.types is an Array like MDN says, whereas Edge says it's "a list of strings" like MSDN says -- note Microsoft's careful avoidance of the use of the word Array.

This is probably an Edge specs-compliance bug, but can Trix avoid using .some on paste.types? It's unfortunate that working around one browser bug (in Safari) exposes another one (in Edge).

Note also that Edge does support Array.prototype.some; the problem here is the object is not in fact a real Array.

Steps to Reproduce

1. Use MS Edge
2. Launch a page using Trix newer than 0.10.2
3. paste

Details

• Trix version: 0.10.2
• Browser name and version: Edge 14 or 15
• Operating system: Windows 10

I'm noticing the same thing happens when you try loading a .some() method into Internet Explorer.
