fix: dont record various commands

[ThisAMJ]

When was the last time someone used sar_hud_inspection? Is it worth cheat-protecting? Certainly looks quite cheaty

Newly unrecorded commands:

• sar_fast_load_preset
• sar_hud_*
• sar_ihud_*
• sar_toast_*
• sar_sr_hud_*
• sar_echo[_nolf]

Modified help strings for:

• help
• sar_<x>_setpos
• sar_hud_order_reset

LMK if there's anything else that deserves not recording :)

whoops: when flags are changed from 0 on certain cvars they are given 0-1 range, because that makes sense.

more precisely, src/Variable.cpp@36

// Boolean or String
Variable::Variable(const char *name, const char *value, const char *helpstr, int flags, FnChangeCallback_t callback)
    : Variable() {
    if (flags != 0)
        Create(name, value, flags, helpstr, true, 0, true, 1, callback);
    else
        Create(name, value, flags, helpstr, false, 0, false, 0, callback);
}
