Add irclog search.

[xet7]

@Quintus could you review this addition of irclog search?
For example, should I use :plainlogdir setting instead of direct path to plainlogs in code?
The same logic works as shell script.
I also tried it with furbot/cinch on my laptop where furbot did load this code, but I had this network error that I could not solve:
Could not connect to the IRC server. Please check your network: getaddrinfo: Name or service not known

A call to #exit will terminate the program (i.e. make furbot quit). I don’t think this is a good idea to use.

That’d be preferrable in case we ever move the directory around. You’ll have to look it up in Cinch’s docs how to retrieve it, though.

I made some notices on some lines of your code, so be sure to review those.

For testing your changes, you can install a local IRC daemon. I use ngircd, which is very easy to configure.

Vale,

It might also be interesting to directly add such functionality to the logplus plugin, as then all logging functionality is capsulated in one plugin rather than scattered around. Then it wil also be easier to retrieve the configuration setting.
