- higher game rounds give more score per field
- pass some info into the player contract
- allow contracts to sit out a turn and not pay gas

- remove frontend sort - players are now sorted in the contract
- remove interactivity - turns are externally triggered
- call new `isRunning` contract method

Game should be enable when all fields are painted. No more turns are
valid then.

- `submit_turn` does the turns for all players now
- A new round is only started after this message was called (not after
each block)
- Everyone can call this message but we will also just submit it in a
loop so the game just keeps running
- Added e2e test that just runs through the happy path of playing a game
with two players

We just want to make sure that once player uploaded their contract we
are not dependent on them submitting transactions. They can just watch
their contracts fighting it out.

In the wake of proposing international workshops, the content
translation has been completed :
- Add Language Selector on the forming page 
- Add Game Rules Translation for the 3 languages

* Add event in Game/lib.rs
* Add fun event messages for the UI using i18n
* Misc cleanup

This reverts commit 3a592f6d.

In order to achieve i18n for the workshop
https://github.com/paritytech/ink-workshop/issues/22,

and complete https://github.com/paritytech/ink-workshop/pull/34, 

most of the content was also translated into French. 

Spanish Translation will follow in another PR.

Previous scoring formula that assigned bonus points based on gas usage
was confusing. Now:

- One point per painted field.
- There is a overall gas limit a contract can use.
- Specified per round on game construction. The overall budget for all
rounds per player is derived from that parameter.

Can be set to some fraction of the gas consumed of the basic player per
round. Only a fraction so that not every block a turn must be submitted
in order to win. Try `500_000_000` (500 us). The less rounds you play
the closer it needs to be to the actual usage to allow for actual turns.

For the UI nothing much changes. I recommend displaying gas left instead
of gas used per player in the player list. Can be calculated by querying
the new `gas_limit` function of the contract and subtracting the used
gas of the player from it.
