This bug covers several string changes in MD extensions.

Notes from Shimi:
[These are in no particular order and are numbered for reference]

(1)
Can we use the Command symbol? 
"Include Control, Alt, or ⌘"? 
(to replace "Include Ctrl, Alt, or Command").

(2)
Change "Need a character" to "Type a letter"

(3)
Change "Find extensions and apps in the [...]" to "Find extensions and themes in the Chrome Web Store"

(4)
In the Details incognito subtext:
[...]showing the string in OFF state is confusing. A simple "string only" solution would be to change the subtitle string to say: 
Warning: Allowed extensions may be able to record*** your browsing history

***Why do we say "recording" your browsing history?? That's not an actual extension permission AFAIK. Should this say "reading" to match current permissions strings?

A more elaborate UI change would be to show different strings depending on the toggle state AND on whether the extension even has the relevant permission.

(5)
Change "Either, not both ctrl and alt" to "Use either Ctrl or Alt"

(6)
Change "Developer website" to "Open extension website"

(7)
Change "View in store" to "View in Chrome Web Store"
