Panic when using -ui-bind-addr (flag redefined: listen)

Problem

I get panic when trying to override the UI or API bind address.

Version

v0.1.6 binary release

Trace:

$ ./MailHog_linux_amd64 -ui-bind-addr=":8026"

[ian-kent]

thanks @nayyden, should have time to look at it this weekend

[nayyden]

Thanks @ian-kent !
I tried to search it in the code but i could not find a registration of the listen flag.

[ian-kent]

it'll be coming from github.com/ian-kent/gotcha, which needs to be destroyed asap 😄 might try and refactor that out this weekend... it was my example of "i'm sure golang needs a web framework", how wrong I was!
