Feature Request: Advanced Permissions Settings that include Contract limits.

[redbrickred]

The default behavior of SwitchDex to ask for an unlimited access limit for contracts is poor design. Setting a limit to unlimited will scare away security conscious users.

Expected Behavior:

• New users should be prompted for a more reasonable default like 1 Ethereum.
• Add a new Advanced setting screen to allow advanced user to increase their limits when they are ready.
• Provide a unique error message when the user encounters the contract limit.
  ** Within the error dialog provide a breadcrumb/link to the Advanced settings (perhaps in another window so the end user can make the permissions change and return to their original trade.)

I am sure there are additional MetaMask WEB3 permissions that the site uses and could be adjusted in a Advanced Permissions like screen.
