Subject: [PATCH] view algorithms on homepage (#388)

* view algorithms on homepage

* linting error fixed

* view algos on rinkeby/mainnet, added algos on search

* global color system tweak, apply on asset teaser system

* create subtle hierarchical distinction between background & content
* output asset type
* add asset type as css class
* bonus side effect: a nicer dark mode theme on OLED screens

* add icon assets

* compute/download icons added to asset teaser

* tooltip content fix

* tooltip content width fix


tooltip message shortened

* max-width added

* links renamed, all algos section removed

* datatoken tooltip removed

* spacing tweaks

* visual separation of asset & access type, flip order
* spacing/font size tweaks, aligning things

* fix search

Signed-off-by: mihaisc <mihai.scarlat@smartcontrol.ro>

* light mode color tweak

* change dataset display name

Signed-off-by: mihaisc <mihai.scarlat@smartcontrol.ro>
