SD shadow QoL and RP improvement

[linusboyle]

I would like to suggest adding some QoL and RPwise improvement to the shadowdancer shadow.

1. Let the shadow copy the PC's Hide/MS

This has been suggested before (viewtopic.php?f=26&t=24845&p=200574) and Irongon seemed to be in favor of it.

Here's why this might be important. A typical SD character has nearly 120 Hide and 90 MS, making it a decent stealther. But the shadow with only 30+ Hide/MS is too frequently spotted and only hinders the PC from doing some shady thing. If the shadow is made to copy the PC's scores, I could anticipate some good extra RP tricks like using Shadow Displacement with a stealthed shadow to simulate a blink effect. It also makes sense IC, since a shadow should be more sneaky than a person after all.

To balance it we could require the feat Epic Shadowlord for this to take effect.

2. Enable languages and emotes

Just so the shadow can do much more in RP, like an illusionist clone. A more fine-grained control is also welcomed. If possible I'd even suggest possessing the shadow like a familiar but that might be too far.

Approved.

WIP. The script needs to be reviewed

1. The hide/ms suggestion has been added.

2. There's something blocking the shadow from swapping languages and using emotes, and I still haven't found it.
   Edit: This is working.
