DDR 'prepares to do battle' message is shown incorrectly.

Discussed in #203

One potential anomaly I've come across is that cf_preparesbattle gets reset unconditionally as part of StartDawn, but then also conditionally at the end of the Night processing as well; this makes me think that it perhaps shouldn't get reset as part of StartDawn ?

the message should be shown in CheckPlace screen whenever a lord is at a location with an enemy.

It needs to be set as part of CMD_Attack / _Approach, and be set/reset at the end of the characters battle turn if enemies still in location. Also reset after a standard move.
