Optional spy outline visibility in first/third person

[Wiethoofd]

Currently ce_outlines_spy_visibility works for invisible spies being spotted from another player's point of view when enabled.

An option to have an outline around an invisible spy's viewmodel in first person and when having ce_tplock_enabled 1 might be nice to have as optional settings.

A few things need to happen in order for this to be closed:

• Need to figure out what's special about viewmodel outlines that causes them to break things (attempting to draw outlines for them was what was causing the white outlines to appear)
• Player glows are currently created/managed by the game, so we'll probably need to completely replace that logic.
