This reverts commit 44eeb3a0.

* Rename `Look Up/Down` to `Spec. Look Up/Down` to disambiguate from `Look Backward`
* Make it support multiplayer replay recording save request too

- They're binary inputs as processed by the game.
- A mechanism for binary inputs with no deadzone is already used for item and drift.
- Generally bound to triggers, not the stick.
- SDL still has a minimum deadzone, so won't fire endlessly.

* A "canon" adaptation of the community-created server option `lessbattlevotes`.
* If set to "None", voting behaves as before.
* If set to "Race" or "Battle". that gametype is considered the preference.
    * The voting screen is always operated from the perspective of the preferred gametype.
    * If you're in an un-preferred gametype, the third vote option will always allow you to continue the gametype.
    * If the preferred gametype is Race and you've just exited a Battle map, Encore may now appear on the second vote option.
* A number of bugs with voting have been corrected.
    * If `kartencore` is on, the third vote option will now correctly have Encore applied.
    * If a custom EXE or malformed packet sends an Encore flag alongside a Battle gametype ID, actively strip it.
        * Just to note, clients do not enter Battle Encore with or without this change - this just prevents a promise the rest of the game couldn't fulfill.

(cherry picked from commit 19aafbfd0b9bde40809ca91195d4636899504708)

Did not get to finish all refactoring or even compile this, I'll continue later

Preview is fairly basic, and only shows players
rewinding. Full state is restored via reloading
the replay and jumping to the timestamp once
the rewind is done.

This makes for smaller replay files while keeping
sync checks in place!

Added the Gametype_Names array and G_GetGametypeByName for ease in converting gametype nums to strings and vice versa

gametype_cons_t is now initialised using the Gametype_Names array, like how Color_cons_t is initialised using Color_Names

# Conflicts:
#	src/doomstat.h
#	src/m_menu.c

Music pausing is now optional.
Sounds may be paused--on by default.
The game itself being paused in off-line mode is now optional.

(showfocuslost now loads from config.)

The first view is also not changed if there are no players to view.

(fickle's suggestion.)

This isn't just a shameless console-empowerement. More precise "spying" can
benefit everybody. But especially in net-replays, this is almost necessary.
