Backend updates

This release marks the end of the dependency on the EVE XML api. MOTKI now uses ESI exclusively!

However, because we are making use of new ESI roles, your characters will need to be re-authorized. I tried to find a way around this but it seems unavoidable.

Additional changes:

• Fixed an issue with handling prompts at the end of a line.
• Added the ability to profile the application by passing the -profile flag. For example:

  $ ./motki -profile cpu
  

  The profiler will write to the current directory in a file named after the profile type. The example above results in cpu.pprof.
  Once you have exited the process, use go tool pprof or go tool trace to review the profile. Continuing the cpu profiling example:

  $ go tool pprof ./motki ./cpu.pprof
