Add the ability to search for irwins

[ya64]

For example, doing +search pines will return an embed with

123 - Dipper Pines Irwin
432 - Mabel Pines Irwin

Note: I'm not sure what the actual numbers for the irwins are we should add this feature quick so I can find out

This will be the main feature of v1.2.0 and will be in the form of +irwin [query], hopefully this should be released soon (I'm just having a bit of trouble generating the jar file)
