Static encounter names

[Sejsel]

Currently, we often use the name of the boss agent as the name of an encounter. This leads to issues if the name was not resolved by arcdps. In that case, we often end up with encounter names like ag734 or ch17632-361.

Instead, localized names for known encounters should be used. For unknown ones, we are going to fall back on the agent name. Currently, we already override some encounter names with their English name.
