Refactor: apply new internal structurs #206

reference: #184

Aim:

restructure but do not change any function
make it more or less compliant with proposed struct

No-Aim:

simplify things based on new structure (i.g. addLoginToConfig & AddLogin)
remove redundant code (if it will need some changes to routines ...)

Refactors:

Move Config & Login routines into config package
Rename global flag var in cmd and move into flag package
Move help func to utils
Move DetailViews stdout print func to print package
Move Interactive Login Creation to interact package
Move (split) subcomands into own sourcefiles
Move Subcomands sourcefiles into it's own Packages
Move print TrackedTimesList to print package

OK this already to that big - so wont add more to this and wait until it got merged to send the next batch (shouldn't be that big but will contain impruvements ... (see TODOs)

How about a subfolder for issues' commands?

How about a subfolder for issues' commands?

what structur do you mean?

instead of issues_subcomand -> issues/subcomand ?

I didn't do a thorough review yet, but generally it looks like a great improvement ?
Some remarks:

modules/intern -> modules/internal (intern means Praktikant and isn't that much shorter ;)

even more descriptive would be modules/config, because it is all about config right now?

move modules/git/auth.go:absPathWithExpansion to modules/util/path.go?
move cmd/times.go:formatDuration() to modules/print/print.go?
modules/interact seems a bit too separated, unless you expect that module to grow significantly?

1. internal is a preserved package name (we can't use that one...)
- I think we can go the "config" way :)
4. yes I think so :) (I like to have more interaction for create comands with no args)
2. &3. I'll look into it
