Add option to show marks instead of title

[ammgws]

This can be merged once tmerr/i3ipc-rs/pull/51 has been implemented.

Solves #486

@ammgws
Sorry for not getting to this earlier, but this works well so far.

Something to consider: I only use 1 mark per window, but sway lets you have several marks per window if you do swaymsg mark [mark1] and swaymsg -- mark --add [mark2] . So maybe multiple marks should get enclosed in brackets like the header bar does?

Also some interesting info from the man page:

show_marks yes|no
           If show_marks is yes, marks will be displayed in the window
           borders.  Any mark that starts with an underscore will not be drawn
           even if show_marks is yes. The default is yes.

I'm not sure if i3status-rust should hide underscores. Marks are not shown by default and there might be unforeseen side effects.

I can look into the multiple marks thing and an option to hide the underscored ones. However if the i3ipc crate is updated before that then we can just merge this simple implementation now and add those features later.

[ammgws]

@travankor this is now implemented using the swayipc-rs crate. It works fine for me, please let me know if there are any issues.

[travankor]

@ammgws seems like it works well but the issues raised here remain.

Also the binary size has gone up a significant bit since the last release -- from 6M to 11M.

[ammgws]

So with one mark set, e.g. "abc", the bar should display: "abc"

And with multiple marks set, e.g. "abc" and "def", the bar should display: "[abc] [def]"

?

If the binary size is a problem then I will have to look into later. Perhaps enabling LTO could help. Do you mean last release as in the last tagged version vs git master?

1. Currently multiple marks get concatenated, and it looks like one giant mark. swaymsg -- mark --add anothermark for example.

2. Marks that begin with underscores are considered hidden by i3/sway.

Yes. It's not a problem for me personally; I just noticed this and wanted to report it.

I don't use marks so I wasn't sure what it looked like in the first place. This is what one mark and two marks looks like for me:

I was thinking about making i3status-rust show multiple marks with brackets around each one like sway does, but looks like sway does it for the singular case as well so I guess I will change that too.

FYI enabling link time optimizations brings it down to 8.6MB
