Upgraded CKEditor to version 4.4.2; Added the missing alignment plugin (#482); Removed the iFrame plugin, which didn't work properly because the SRC was being stripped out by input filtering.
Select the first Community Type by default instead of forcing user to select one.
Minor typo fixes.
Closes #478: $member was being address as an array value, removed array key reference.
Refs #481: CSV importer defaulted organization ID to 0, relying on course's organisation. When it failed on a course code that didn't exist the org was still 0, resulting in everything organizationally aware to fail. Sets default value to user's active organization, and overrides it when a course code is found.
Refs #478: Fixes same issue with member should not be an array element.
Fixed a couple minor issues. Removed a line disabling the debug flag for adodb, and changed the assessment delete to disable the assignment associated with it as well, rather than setting the assessment_id for that assignment to 0.

  Refs #478: Fixes same issue with member should not be an array element.
Removed duplicate database upgrade file. The change being made in 1617 was identical to the one being made in 1614.
Ref #497. Added in a default_org_id variable for javascript to use that is declared in the init file, then removed some declarations that would result in the org_id variable being set to the same value, and changed the logic of the objectives.js api calls to use the default_org_id if not org_id is defined in javascript. Also changed the api call itself to make it use the user's current organisation if that variable isn't provided.
Removed a PHP short tag that causes a fatal error in some environment (where short tags aren't enabled on newer versions of php), and changed the formatting of the code a bit around that spot.
Minor UI adjustments, and a fix for my previous fix which adjusts for Bootstrap label styles.

Refs #498, checks if the user is logged in before setting the default_org_id in JS.
Refs #499, fixes buggy manage community html with no admins enrolled.
Refs #495, makes InteralAwards::sort() compatible with Collection superclass.

The declaration of the sort function in InternalAwards didn't quite match the declaration of Collection::sort().
Ref #496. Fixed a few issues with the evaluations module. Firstly, made sure the organisation ID sticks around when editing questions of the rubric type (and that it doesn't change to the user's current organisation rather than staying at what the question was initially, for all question types), then also made the descriptors api call fail more gracefully if no descriptors exist- while adding in some defaults to the database as well, and finally, removed the requirement for a "request" to exist for evaluations with them enabled, unless it is explicitly required.
Install and upgrade SQL fixes preparing for the 1.6.0 release.
