Allow context keyword substitutions in FPP

I can now see the checkbox but it doesn't save the value when selected. Going back into the pane and it's unchecked

I get empty contexts even though there is a context in my panel :/

Warning: Invalid argument supplied for foreach() in ctools_context_keyword_substitute() (line 639 of DRUPAL/profiles/quequere/modules/contrib/ctools/includes/context.inc).

btw, I also get issues for fields that are not text-type, I've fixed with a !empty check.

The reason for the empty contexts is that a content type only receives requested contexts unless it sets 'all contexts' => TRUE in its definition. Then it will always receive all contexts. Since FPP shouldn't be requesting contexts that I can think of, this should be fairly safe to set.

@merlinofchaos actually, 'all contexts' => TRUE is set: http://drupalcode.org/project/fieldable_panels_panes.git/blob/refs/heads... :/

Right now I'm monkeypatching ctools to call fieldable_panels_panes_fieldable_panels_pane_content_type_content_type when needed (in ctools_content_select_context because calling it in ctools_content_select_context always led to out-of-memory errors).

I figured the 'content type' key in plugin definition was missing (not sure if this is the proper way to declare it though). Then I found out that fieldable_panels_panes_fieldable_panels_pane_content_type_content_type and fieldable_panels_panes_load_entity would call each other in a loop, so I fixed it by taking a shortcut to _fieldable_panels_panes_load_entity.

Now the contexts are passed to the pane and everything works. I've fixed a small issue with fields that don't set the #markup property, such as link fields.

Added support for title links as well.

Reroll of #13 against latest dev.

Works great for text fields. Is there a way to get this to work for image fields as well? I'm using the Media module and there is no way to add a token substitution through the UI.

Last patch works as expected.

Rerolled patch in #14 against latest dev.

This needs some tests to confirm it works. Also, this line needs to be rewritten to not have the word "you" and make the URL a link:

+ $description = t('If checked, context keywords will be substituted in this content. More keywords will be available if you install the Token module, see http://drupal.org/project/token.');

Re-rolled patch, with fixes as outlined by DamienMcKenna.

I have re-rolled the patch mentioned in #20 as FPP has meanwhile declared additional update hooks.

Well, that was a hot shot, didn't expect so many changes inside FPP.
Here's the updated patch.

Moving to "Need review" to let DrupalBot pick this patch for testing.

This patch is a reroll of #23 against current DEV and takes care of the entity "path", that may need substitution.

Needs tests.

Hiding old files. Might try to fix this up. @DamienMcKenna, do you know what tests are needed at a glance?

Patch did not work on new FPP version, needed to rename hook_update_N().

Fresh patch for dev / 7.x-1.13.
