Extension crashes when opening a nim file

[fredrikhr]

From the crash log it seems this is a timeout issue when launching nimsuggest. There should be configuration setting to enable users to set their own timeouts.

Yes, the log states that I am using nimsuggest compiled from devel, but I have confirmed that the same issue occurs on vanilla 0.17.0 nimsuggest.
