With this patch forward this will be the only way for
a contract to destroy itself. This patch therefore changes
the semantics of all other contract initiated balance
transfers to fail if they would bring the caller below the
existential deposit.

* contracts: Add ext_transfer call

This call allows contracts to send balance to any account
contract or not. Previously, the only way to do that was
though ext_call.

* contracts: Allow to distinguish out of gas from other traps

When a contract encounters a runtime error a wasm trap is
triggered and the execution is halted. Currently, no matter
what was the cause for the trap it is always reported as:
DispatchError::Other("contract trapped during execution").

However, the trap that is triggered if a contract exhausts
its gas budget is particulary interesting. Therefore we add
a seperate error message for this cause:
DispatchError::Other("ran out of gas during contract execution").

A test is added hat executes a contract that never terminates.
Therefore it always exhausts is gas budget.

* fixup! contracts: Allow to distinguish out of gas from other traps

Remove overlong lines.

* contracts: during execution -> contract trapped during execution

This message confused many people so we are improving it to make clear what happened.

* contracts: rename Event::Contract -> Event::ContractExecution

* contracts: fix tests after ContractExecution renaming

* contracts: Add Evicted and Restored events

* fix doc comment

* wrap to not go over (soft) 100 column line limit

* add event deposit for eventual eviction upon pay_rent

* contracts: adjust tests for the new events

* emit Evicted event immediately and add tombstone flag bool

* Make `decl_error!` errors usable

This pr implements support for returning errors of different pallets in
a pallet. These errors need to be declared with `decl_error!`.

The pr changes the following:

- Each dispatchable function now returns a `DispatchResult` which is an
alias for `Result<(), DispatchError>`.
- `DispatchError` is an enum that has 4 variants:
  - `Other`: For storing string error messages
  - `CannotLookup`: Variant that is returned when something returns a
  `sp_runtime::LookupError`
  - `BadOrigin`: Variant that is returned for any kind of bad origin
  - `Module`: The error of a specific module. Contains the `index`,
  `error` and the `message`. The index is the index of the module in
  `construct_runtime!`. `error` is the index of the error in the error
  enum declared by `decl_error!`. `message` is the message to the error
  variant (this will not be encoded).
- `construct_runtime!` now creates a new struct `ModuleToIndex`. This
struct implements the trait `ModuleToIndex`.
- `frame_system::Trait` has a new associated type: `ModuleToIndex` that
expects the `ModuleToIndex` generated by `construct_runtime!`.
- All error strings returned in any module are being converted now to `DispatchError`.
- `BadOrigin` is the default error returned by any type that implements `EnsureOrigin`.
