admin2: Add resource settings cache

[ghost]

As suggested in #162 i've added caching for resource settings.

Issue #162 seems to be talking about preventing repeated reads for settings related to the admin resource.

Shouldn't we only be caching the admin resource's settings? I think it's fine to fetch fresh settings when using the settings editor.

Although admin2 has these (and only actually reads the consolecommands setting).

mtasa-resources/[admin]/admin2/meta.xml

Lines 249 to 274 in 284e948

	<settings>
	<setting name="#pingkicker" value="0"
	group="Automatic scripts"
	friendlyname="Ping kicker"
	accept="0-1000"
	desc="Max ping allowed (0 - off)"
	/>
	<setting name="#fpskicker" value="0"
	group="Automatic scripts"
	friendlyname="FPS kicker"
	accept="0-100"
	desc="Lowest fps allowed: 25-75 (0 - off)"
	/>
	<setting name="#idlekicker" value="0"
	group="Automatic scripts"
	friendlyname="Idle Kicker"
	accept="0-100"
	desc="Maximum time a player can stay idle (minutes, 0 - off)."
	/>
	<setting name="#consolecommands" value="[true]"
	group="General"
	friendlyname="Enable console commands"
	accept="[true],[false]"
	desc="Parse console commands."
	/>
	</settings>

And admin1 has many more (I haven't checked if they are actually in use):

Other style stuff:

• your patch uses tabs, but it should use spaces
• blank lines should be empty / not contain any whitespace
• please add a space after the if keywords - if (...) then, not if(...) then
