Feature sc apis

[localhuman]

What current issue(s) does this address?, or what feature is it adding?

Adds additional functionality covered in these features for neo core:

• Dynamic Invoke: [NEP4] Feature-dynamic-invoke verification neo-project/neo#120
• Neo.Runtime.GetTime: Adding Neo.Runtime.GetTime and Neo.Runtime.GetCurrentBlock neo-project/neo#122
• Neo.Transaction.GetUnspentCoins: Adding Neo.Transaction.GetUnspentCoins for issue #114 neo-project/neo#123
• Neo.Header.GetIndex: Adding Neo.Header.GetIndex for issue #114 neo-project/neo#121

These work in conjunction with changes to currently in the neo-boa development branch

Are there any special changes in the code that we should be aware of?

Main change is that when building a contract or importing one, you now need to specify whether a contract needs dynamic invoke or not, same as you do with storage. So this:

> build ../path/to/file.py test 0510 05 True name []

Would now be this:

> build ../path/to/file.py test 0510 05 True False name []

Unless you want your contract to be able to invoke other contracts defined at runtime, in which case it would be this:

> build ../path/to/file.py test 0510 05 True True name []

Same changes apply to the import contract command:

> import contract path/to/file.avm 0510 05 True

Should now be this:

> import contract path/to/file.avm 0510 05 True False
