MDL-36640 Logging: Correct testing of log->info.

log->info sometimes contains additional information which can be looked up
from other tables. This should only be attempted if the field is numeric,
but the CSV, XLS, and ODS outputs were not making this check.

There is an additional case for the print_mnet_log function which has not
been covered - this is because the mnet logging is currently broken beyond
the scope of this bug rendering this section untestable. These issues are
raised in MDL-36642.
MDL-36167: Update all users in assignment quickgrade form to ensure feedback is saved
MDL-36167: Assignment quickgrading fix when there is no grade (ensure feedback still saves)

This patch modifies the previous on by Luke Tucker so that the lastmodified hidden field
is always added to the quickgrading form even if there is no grade for the assignment. This
ensures that the lastmodified checks still work (to prevent teachers overwriting each
others feedback) and feedback is saved when there is no grade.

MDL-36736 course: Availability information should not be visible for hidden modules

If user is viewing hidden module, availability information should only be visible to
user when editing and module is visible. If editing and module is hidden, then hide
availablilty information as it's invalid.
When user is not editing and activity is hidden then don't add availability information.
MDL-32880: moodle1 backup converter: add generic block handler

This handler will automatically be used for any block which does not provide its own handler, and should be subclassed by any block which needs to do anything extra (or different).

This commit incorporates contributions from Mike Churchward and API design suggestions from David Mudrak.
MDL-32880: Add moodle1 backup converter for html block.

This converter processes the HTML block's content, migrating any referenced files.
MDL-32880: Add moodle1 backup converter for rss_client block.

Creates a shell rss_client.xml file, which contains no feeds.  This makes it behave the same as restoring a Moodle 1.9 backup into a different 1.9 site - the block is created, its title is as per the original course, but it has no feeds selected (and none are added to the site's feed list).
MDL-36650 don't change question timecreated or timemodified on restore.
