Syslog type should be a string

[MPM1107]

Just solved an issue someone on the discord was having. His z2m was crashing when he tried using the new syslog feature.

His config and log:

Turns out that the type being set to 5424 was breaking it, because match() only works on strings, so setting it to '5424' fixed the issue. So this should either be clearly stated in the documentation, or some code should be added to cast the int to a string.

Fixed in latest dev branch, thanks for helping out!
