Security Check in Progress v7.0

A lot of bugs have been fixed with this update. deleteChar now works
differently for the whole scene deletion (no delay or animation) and for
individual character removal (delay and animation is present.)
The initiative fields are now checked inside the nextPhase() before
findMax() will run.
sceneLoad() got fixed and tailored to the new deleteChar(). Now, all the
characters are removed properly upon another scene load.
The highlighted characters, after the highlight was gone, were all
becoming PCs. Now, they are returning back to their correct status: PC
or NPC.

To Do:
make a unique check for the sceneName input field.
