Default properties are formed as:

Note that all properties *except for* `DamageFunction` require `Expression` to
be a constant expression.
There are several special properties which add pre-defined flag sets onto the
actor. Here is a list of them:
| Name | Description |
| ---- | ----------- |
| `ClearFlags` | Clears all flags except `ARGSDEFINED`. |
| `Monster` | Adds the flags `SHOOTABLE COUNTKILL SOLID PUSHWALL MCROSS PASSMOBJ ISMONSTER CANUSEWALLS`. |
| `Projectile` | Adds the flags `NOBLOCKMAP NOGRAVITY DROPOFF MISSILE IMPACT PCROSS NOTELEPORT`, and if the game is Heretic or Hexen, `BLOODSPLATTER`. |
Note that like any other property, they require a semicolon after them,
although they do not use an expression.
