Use (partially) condensed in shrinking subsystem

[CWempe]

Is your feature request related to a problem? Please describe.
I want to save space in my shell.

Describe the solution you'd like
When the -max-width is reached the -condensed mode could be used before the modules get stripped away.
Maybe partially first, then fully condensed.
And only if that does not help enough, the modules should get stripped away.

This could be implemented in the -priority option by the keywords condensed-first and condensed-last (or first-space and last-space).
So the user can define wich spaces should get deleted and in what order.

Describe alternatives you've considered
