mint-arena: Fix Team Arena SP win/lose msg in CTF using q3_ui

Create new function TossPlayerGametypeItems.

Backported from Turtle Arena.
mint-arena: Separate holdable values from EV_USE_ITEM# events

Makes it easier to find the code when searching for HI_MEDKIT etc.
Allows reordering holdables without breaking using them.

Make the game holdable code more similar to CG_UseItem as well.

mint-arena: Drop Harvester cubes when entering Team Arena holdable portal

Makes it consistent with using holdable teleporter.
mint-arena: Make Harvester cube drop in a circle when use holdable teleporter

This is done for powerups. Makes dropping many cubes look better, maybe.

Don't draw client console buffer past top of screen

Thanks @Pan7.
mint-arena: Make refEntity_t shaderTime be an int instead of a float

Converting time to a float results in precision loss at long uptimes.

This commit doesn't fix that, but should be possible to fix by only changing engine now.
Restore drawing a cut off client console line in 1920x1080

The text lines don't meet at top of the sceen in 1920x1080, restore
drawing a cut off line across the top. In 640x480 this line isn't seen
at all. This is still better then trying to draw twice as many lines
than are actually seen (the way it was before the last commit).
Fix fast-math optimize flag for MinGW x86_64 build

Found by /dev/humancontroller.
mint-arena: Add hours column to game timer

If game time is over an hour, add a hour column to CGame time display.
mint-arena: Track digital and analog key state fractions separately
mint-arena: Use separate cvars for digital and analog angle turn speed

The default turn speed was too slow. Increasing it makes aiming using
keyboard a lot harder. So use separate cvars for analog and digital.

Using analog and digital at the same time now adds both. This is just
a side effect and doesn't matter enough to fix.
mint-arena: Make joystick analog fraction be 0 at threshold

Scale the axis value so that edge of 'dead zone' aka threshold is 0.
Makes aiming using analog stick a little better (feels more sensitive).
mint-arena: Rename trap_DropClient to trap_DropPlayer
mint-arena: Add flares to video settings

Saw it in Open Arena, seems like a good idea.
mint-arena: Fix over draw in CG_DrawRect

It was noticeable in the corners when alpha was less than 1.
mint-arena: Add effects color 2 to player settings

Backported from Turtle Arena. Added caption for what they control.
mint-arena: Add handicap caption in menu like Open Arena

Added "of a " because I think it sounds better.
mint-arena: Add more player effect colors

color1/color2 cvars can now be set to 8 to 13 for new colors.

In the UI, if the artwork piece for a new color is missing,
the white artwork is used and colorized.
