Add a 'Services using this song' section to the Service Component Library, plus 'Disable' and 'Delete'

[jefft]

I've added some new features to the Service Component Library:

• 'Services using this song' panel showing uses
• 'Disable' button, which removes associated congregations in one click
• 'Delete' button, for components that are not used on any runsheet (How to delete a Service Component Library item #906).

Also, the page now loads the song indicated by the service_componentid URL param. Clicking a song updates the URL with this parameter, so you can bookmark or send a URL to someone.

Todo:

• Set the page title to the loaded song name, so bookmarks make sens.
• Change terminology from 'Song' to 'Service Component'

Good ideas. Feedback so far:

• "Services using this component" ought to be within the song details box, rather than a separate box, I reckon.
• The delete and disable links ought to have a confirmation popup box (like other 'delete' actions in Jethro). This is also an explanation of what 'disable' means.
• I wonder if "disable" is the right word. Maybe "archive" is better? I think that's more consistent with the rest of Jethro, eg an archived person isn't in any congregation.

Thoughts on thoughts:

Hm, but the service-song relation is independent of both the service and the song. It isn't "part" of the song, and more than it is "part" of the service. The 'Edit' button doesn't apply to service-song relations:

The delete and disable links ought to have a confirmation popup box (like other 'delete' actions in Jethro). This is also an explanation of what 'disable' means.

I don't like confirmation pop-ups (imagine trying to delete 50 CSV-imported songs...), but I guess 'Delete' could have one, since it's a non-reversible operation.

'Disable' is fairly reversible, and the fact that "Congregations" goes blank right before your eyes is a bit of a hint as to how it works. WDYT about leaving 'Disable' popup-free, but immediately replacing it with 'Enable...':

then with a modal listing the congregations to re-associate the song with?

I wonder if "disable" is the right word. Maybe "archive" is better? I think that's more consistent with the rest of Jethro, eg an archived person isn't in any congregation.

Well, this business of disassociating congregations is really a hack. From a user's perspective, clicking 'Archive' should archive the song with congregation relations intact, and clicking 'Unarchive' should restore things just how they were.

Perhaps "Disable" and "Enable for.." is more true to the underlying reality than "Archive" and "Unarchive for..". "Unarchive for.." doesn't really make sense.

But whatever you prefer on all this stuff, LMK and I'll tweak the patch!

I've made two changes:

• Delete now has a confirmation pop-up
  
• 'Disable' has rollover text explaining what it does
• Disabled songs have an 'Enable' link, that takes one to the song edit page highlighting the Congregations, with instructions to edit them. After editing, one is taken back to the same song in the component library:

PS: The highlight-a-field support is done with newly added hl ("highlight") and hltext URL params, added as a separate commit in this PR.

Layout issue:
On a mid size laptop screen, the usage box shows on the left

(This would be solved by putting the usage info into the same box as the other stuff ;-) )

I created #1333 to fix this.
