Implement Dynamic Build of Coin List

[chrislennon]

Coin list may be dynamically generated from API https://www.cryptocompare.com/api/data/coinlist/

This may however bring in interesting considerations with coin icons and will build in a dependancy to external API to the app's load.

1895 coins are returned from the API, with no obvious sorting parameter... some thought required on this 😟

[chrislennon]

Some further thought on this...

• UI will need a refactor for this, there is no way displaying ~1900 coins is a sensible way forward
• Make use of something like selectize to provide a searchable dropdown
• On selection of the item from dropdown add it to the main window & touchbar and provide colour change functions

Pros:

• Will provide a lot of futureproofing in the sense of addition of new coins
• Speed up load times of page as wont need to load large amount of SVGs

Cons:

• rework/refactor the UI
• Unsure how to tie the icons/SVGs to the populated list - maybe on the ticker (however wont cover the usage of -ALT icons, for example IOTA-alt)
