Smart contracts should be given access to accounts for apps specified in the foreign apps array

[algoanne]

Problem

Currently, I have to separately specify the account for an application if I want to use it in my smart contract, even if I already specified the application itself.

Solution

Make it so the smart contract automatically has access to the app's address if it specifies the app in its foreign apps array.
