Add links with icons to extended profile

[x] make profile form "hydrate/dehydrate" link values from json array to list of inputs
[x] add incrementing of link inputs in profile form (made implicit in MVP, no + button)
[x] add icons to timeline in styled bubbles, under bio
[ ] ~~add tooltips to timeline bubbles~~ not in MVP, use callto: for phones in browsers

We stumbled upon a form refactoring when implementing this, steps:

[x] there's a bug in profile form links caused by preserve-inputs package
[x] preserve-inputs package has been disabled
[x] register/login/post create forms now lose their values after submit
[x] we need to pour all form input data into reactive data of ReactiveTemplate subclass
[x] we need to refactor all forms to work around form data and not model data
[x] forms should preserve focus after re-rendering
[x] forms shouldn't re-render when switching between admin tabs
