Suggest playing time to DoF when renewing contracts

[Platinum]

When telling the DoF to renew contracts we should be able to tell the DoF what we want the playing time of the player to be.

We can do this when the DoF is making a transfer so we should also be able to do it with contract renewals. 

The problems the absence of this feature causes is that sometimes the DoF will offer a player too low a playing time and this means the contract renewal fails (for example the DoF sometimes offers "Backup" to a player that is a "First Team Regular". Aso for many young players the DoF might think a player doesnt have much potential, whereas I think they do, and then the DoF offers the player a playing time which is too low and the player rejects it, which means I lose high potential youth players.
