fix 'CBA_fnc_peak'

[commy2]

When merged this pull request will:

• call compile _varName replaced with missionNamespace getVariable _varName
• reduce network traffic by using the new CBA_fnc_serverEvent and CBA_fnc_ownerEvent instead of CBA_fnc_globalEvent twice
• fix example was wrong (cba_diagnostics_receive_peak has a S too much)
• fix CBA_fnc_peek is broken (undefined GVAR instead of QGVAR):

18:52:49 Error in expression <nostic\peek';
params ["_variable"];



[cba_diagnostic_peek, _variable] call CBA>

• formating

Since the function was broken anyway and actually never worked, we might as well fix the spelling and rename it to CBA_fnc_peak instead of CBA_fnc_peek

[commy2]

Alternatively, we just remove this. It doesn't actually seem all that usefull.

peek was the right spelling

[commy2]

Ok. But then it was misspelled here: https://github.com/CBATeam/CBA_A3/blob/master/addons/diagnostic/XEH_preInit.sqf#L16

server To receive

Probably missing a point? I'd also get rid of the usage code from this description, it has no place to be here, but in function header.

[PabstMirror]

If it's been broken for a long time that probably means no one is using it, could just remove.

[commy2]

According to github, it never worked. At least not since 2009.

Peek, not peak, as mentioned.

[Killswitch00]

Function removed, since it's been broken for so long.
