Cleanup assets folder

[benoit74]

Too many assets are stored in the assets folder.

• all assets retrieved from iFixit current website have been stored, but probably some of them are useless, either in terms of file but also in terms of CSS code (beware that the site is responsive and hence many CSS is used at different breadcrumbs for instance)
• some old assets linked to the old homepage way of work can be removed since unused

To be confirmed if this is a viable effort (not too much time to be spent for something which will quickly become outdated as we will update to new iFixit layout/design) + how to do this reliably ?
