Mako88 reports that some users want not to autoselect while firing, but
do not notice when a new weapon is added to the HUD, and end up never
activating a preferred weapon. Add a new autoselect mode that remembers
what would be selected and switches to it once the player ceases firing.
Changes since Mako88's proposed version:
- Use `enum class` for autoselection mode and a radio button to
represent the decision of Immediate/Never/Delayed.
- Handle delayed autoselect for vulcan ammo.
- Set Delayed_primary == Primary_weapon to indicate no change is needed,
rather than Delayed_primary==-1. This lets some paths use
Delayed_primary without checking for a magic value.
- Likewise Delayed_secondary / Secondary_weapon.
- Update Delayed_primary/Delayed_secondary when changing active
primary/secondary weapon, so that a player who changes weapons while
firing will automatically clear any deferred change.

Previously, Rebirth on __unix__ always set the write directory to
"~/.d*x-rebirth" (or "~/Library/Preferences/D*X Rebirth/" on Mac). Add
$D*X_REBIRTH_HOME and $REBIRTH_HOME to override it. If
$D*X_REBIRTH_HOME is set, use that. If not, then try $REBIRTH_HOME. If
that is also unset, then use the hardcoded default.
Add option to compute indirect includes even when not necessary, since
indirect includes influence the inclusion count shown in the comments.
Enabling this option makes SCons work harder for the same output binary.
It should only be used by developers who want to see precise file
inclusion counts.
Autoselect from pick_up_vulcan_ammo only ever armed the Vulcan cannon,
even if the user has and prefers a Gauss cannon. This is probably an
oversight from when D2 weapons were added. Rework the pickup logic in
D2 so that the more desirable of Vulcan or Gauss is picked.
