Improve Generate Link for users without Massa Station

[thomas-senechal]

This is a proposal and still WIP

Context
We have a "generate link" feature that allows users to generate a link to request coins. They can then send this link to another user. This link will open the Massa Wallet module on the send coins page with the address and amount fields already filled.
Generated links looks as follow: https://station.massa/plugin/massa-labs/massa-wallet/web-app/send-redirect/?to=...&amount=...

When a user opens the link, they will either end up on the send coins page, or an error if Massa Station isn't running or if the user doesn't have Massa Station installed.

To avoid users ending up on an error page, we could redirect users to a web2 website page, for example, station.massa.net. So we would endup with a link like: https://station.massa.net/send-redirect/?to=...&amount=...

This page will check if Massa Station is running:

• If so, we redirect to https://station.massa/plugin/massa-labs/massa-wallet/web-app/send-redirect/?to=...&amount=...
• If not, we tell the user that we couldn't detect Massa Station running, they can install it (with a link to it), or open it (we can probably automate Massa Station starting, but a first version just telling people to open it is fine IMO). And, we display the Address that requested the amount and the requested amount so if the user doesn't want to install Massa Station, they still have the information to send the requested coins.

I think it could help us to improve user experience, even for people that does not have Massa Station installed, and that would also promote a Massa Station when users start using the generate link feature

Note that in case of Massa Station not detected as running, we could probably also use the Wallet Provider to allow users to send coins directly from the page using a web browser extension.

@thomas-senechal thanks for starting this topic!

Priority-wise:
We will need to discuss a few different solutions regarding your proposal after the ICO quest release. For the ICO quests we will go with the currently implemented functionality and flow.
