Ensure the page can be pinch to zoomed

NickColley · NickColley · commit 976e316156ed · 2019-11-14T11:16:41.000Z
I've tested in latest versions of iOS and Android. - iOS v10 onwards ignores disabling pinch to zoom - Android does not ignore disabling pinch to zoom, although the user can override this. I have not been able to introduce any negative impact for removing pinch to zoom, the interface scales proportionally and does not obstruct anything. So given that iOS already ignores this I think we should allow this for all users. This is also a WCAG accessibility requirement. Fixes #110
