[WIP] Replace ConciseContract with ContractCaller.

[Exef]

What was wrong?

Related to Issue #1025

How was it fixed?

I renamed ConciceContract to ContractReader and ConciseMethod to ReaderMethod. Also removed all unwanted methods allowance from ReaderMethod.

TODO:

• Write documentation to the ContractCaller
• Write test for the ContractCaller
• Write test for deprecation message for ConciseContract and ImplicitContract

The description of the work in #1025 is lacking. Rather than replacing, ConciseContract should have deprecation warnings added, and the ContractReader should be added as a new feature. After the next major version bump, ConciseContract can be deleted (v6). Going through a deprectation cycle will allow us to not break anyones code that depends on ConciseContract, and give them ample time to update before it is removed.

@Exef Im going to update the description. The ContractReader object needs some more discussion surrounding the spec that can happen in the issue #1025.

[Exef]

ok, I'll update this PR in that way.

BTW, if you rebase against master, the doctest failure will go away.

Hi @Exef! I started working on this same issue to get familiar with the library and saw this. Are you interested in completing the todos you have listed above or can I finish it up? :)

This has been implemented in #1227. Thank you for the effort @Exef!
