[FEATURE] Display multiple lists when provided multiple options

[jmakhack]

Currently the program will only display the list of the last option provided.

For example:

$ mya -wcdh jmak
onhold 2 anime
1. Commit on Titan
2. My Neighbor Octocat

---

This enhancement is to display all the lists provided within the options.

For example:

$mya -wcdh jmak
watching 1 anime
1. One Push Man

completed 3 anime
1. GitBoy
2. MasterBranch Z
3. MasterBranch Z: Season 2

dropped 1 anime
1. Re:Base

onhold 2 anime
1. Commit on Titan
2. My Neighbor Octocat

This would probably require changing the enum in the arguments struct to either individual fields or making a nested struct containing the different modes. Is there any other approach you can think of? I can work on this issue.

@sameersecond, the first approach that came to mind when writing this was splitting up the enum into multiple fields similar to the SFW option you worked on.

The other approach of creating a nested struct containing the different modes may actually be nicer though since it keeps all the "mode" options together in a single data structure. No other approaches come to mind at the moment. I'm open to any approaches for this issue.
