Add entity names to "MOVETYPE_FOLLOW with no model" warning
Implement CTRL+Backspace and CTRL+Delete for text entries
Try to prevent game breaking states with silly values of m_yaw/m_pitch
Minor cleanups
Added "session_begin_ignore_version" hammer command
* If you brick your VMF with this, don't blame me
Add description to r_PhysPropStaticLighting
Move "dynamic shadow poke through" "fix" to opt in convar
* r_shadow_clip (defaults to off) - it being enabled causes shadows to be clipped erroneously sometimes
Try preventing "non positional" control points bloating particle bbox
* This should help with particle sorting
* Marks C_INIT_RandomColor C_OP_RemapAverageScalarValuetoCP C_OP_RemapCPtoScalar as using non positional control points (in addition to the existing ones)
* This could potentially cause issues where these non positional operators act on positional control points used by other control points, but who would do that?
