As a user I fund issues in the project's native ERC-20 token

[gerbert-vandenberghe]

Context

At the moment funding is only possible in the FND token. In the FundRequest platform contract it is possible to specify another ERC-20 token that is allowed to fund issues in a certain repository. The front end should support this by:

• displaying the funding in multiple ERC-20 tokens;
• allowing to fund in other ERC-20 tokens as FND when adding funding to an issue.

Flow of events

1. The funder chooses to add funds to an issue on a repository that allows funding in another token as FND.
2. The Github browser plugin displays the funding dialog with the option to choose the token to be used.
3. The user chooses which token he want to use.
4. The user adds te funding to the issue.
5. When the transaction is processed the funding is displayed on the issue. In case of funding in multiple tokens the funding in the different tokens is diplayed.

Additional info

• FND is the default choice to add funding
• It is possible that an issue is funded in FND and the repository's native token. Both have to be displayed on the overview screen of issues and the detail screen of issues.
