[FEATURE REQUEST] Align file icons and colors

[tbsbdr]

Problem
Icons and Icon colors are quite different between web and mobile clients. This is particularly noticeable when I e.g. do presentations, see screenshot.

Proposed solution

Align icon style and colors between web and mobile clients.

@JuancaG05 @jesmrec Whats you opinion - do you consider the proposal an improvement?

[jesmrec]

yes, that's an improvement. We just need those icons from somewhere.

[JuancaG05]

Hey @tbsbdr! Yes, I agree with that. But, as @jesmrec states, we need to take those icons from somewhere, since the ones we have now come from long time ago. Would be cool to have some kind of "common database" to share the same icons (we don't receive them from server, they are saved locally in the app data), also if there is any new type of file added in the future 👍

[tbsbdr]

We could proceed like that:

1. replace current icons with the proposed one (same as web)
2. discuss centralised icon set (not sure if this approach will be a benefit, as clients will always need some set of local icons - tbd)

The proposed icons are taken from web, resource-type-*.svg

• https://github.com/owncloud/web/blob/master/packages/design-system/src/assets/icons/resource-type-pdf-fill.svg I've extracted the colors web via browser inspect eg from: https://ocis.ocis-web.master.owncloud.works/

mabye @kulmann and team can provide more structured guidance 🙏
