Add toggle button to hide/show R input lines in screen output

[hupponen]

Summary

• Adds a 'Hide input lines' / 'Show input lines' button next to the Screen Output title in the job details view
• Button is only shown for R tools (tool ID ending with .R)
• Clicking the button filters out lines starting with > (echoed R input commands)
• Button is right-aligned, consistent with the Cancel all button style
• Filter state resets when switching to a different job

1. I tried this in an example session "08_microbial_community_analysis_16S_preprocessing_ASV_DADA2" and selected the latest job. Does R use also "+" to mark code blocks?

> if (fileNotOk("multiqc_report.html")) {
+   system("mv stderr.log error_log.txt")
+ }

When this is enabled, the last two lines stay visible. Those should probably be hidden too?

2. We could think about enabling this by default.
3. My first test session didn't have any ">" -characters, which made me think if the button should be disabled until there is something to hide. But this session was probably from the old client, so this shouldn't be an issue anymore.

1. Good point, fixed.
2. Thought that too, input lines now hidden by default.
3. Ended up hiding the button if no input lines, looks cleaner that way. Also with disabled, it's sometimes not super clear if the buttons is disabled or not, especially with the grey 'secondary' buttons.
