- Further work on mechs.

- Turrets should now target mechs (there's a possibility of nasty errors there).
- Global iterator datum (just for lulz. Check readme inside global_iterator.dm and mecha.dm for examples).

+README:
+
+The global_iterator datum is supposed to provide a simple and robust way to
+create some constantly "looping" processes with ability to stop and restart them at will.
+Generally, the only thing you want to play with (meaning, redefine) is the process() proc.
+It must contain all the things you want done.
+
+Control functions:
+	new - used to create datum. First argument (optional) - var list(to use in process() proc),
+	second (optional) - autostart control.
+	If autostart == TRUE, the loop will be started immediately after datum creation.
+
+	start(list/arguments) - starts the loop. Takes arguments(optional) as a list, which is then used
+	by process() proc. Returns null if datum already active, 1 if loop started succesfully and 0 if there's
+	an error in supplied arguments (not list or empty list).
+
+	stop() - stops the loop. Returns null if datum is already inactive and 1 on success.
+
+	set_delay(new_delay) - sets the delay between iterations. Pretty selfexplanatory.
+	Returns 0 on error(new_delay is not numerical), 1 otherwise.
+
+	set_process_args(list/arguments) - passes the supplied arguments to the process() proc.
+
+	active() - Returns 1 if datum is active, 0 otherwise.
+
+Misc functions:
+
+	get_last_exec_time() - Returns the time of last iteration.
+
+	get_last_exec_time_as_text() - Returns the time of last iteration as text
+
+
+Control vars:
+
+	delay - 	delay between iterations
+
+	check_for_null - if equals TRUE, on each iteration the supplied arguments will be checked for nulls.
+	If some varible equals null, the loop is stopped.
+	Usefull, if some var unexpectedly becomes null - due to object deletion, for example.
+	Of course, you can check the variables inside process() proc to prevent runtime errors.
+
+Data storage vars:
+
+	result - stores the value returned by process() proc
