- Added flags for A_SpawnParticle and angle parameter.

Browse source 
- SPF_FULLBRIGHT makes the particle full bright.
- SPF_RELATIVE encapsulates the following flags:
- SPF_RELPOS: Position is relative to angle.
- SPF_RELVEL: Velocity is relative to angle.
- SPF_RELACCEL: Acceleration is relative to angle.
- SPF_RELANG: Add caller's angle to angle parameter for relativity.
