- Fixed issue with app not responding to https requests
- Added configuration for ignoring/considering lti key/secret
- Extended logParameters to show them ordered

The parameter custom_mode=[simple|extended] overrides the mode set by default in lti.properties

bbb-lti: Changed the main tool title shown by the lti cartridge

[x]Views now are localized
[x]Added sp and fr translations
[x]Updated icons. icon.ico(16x16) icon.gif(24x24)
[x]Parameter custom_bbb_record is now custom_bbb_recording
[x]Removed not required files
[x]Changed behavior of extended mode. Users join directly if the recording is mot enabled for the launch.

I'm re-applying this code after reviewing the 0.1.1 version of bbb-lti. From my testing, an LTI's custom welcome message is currently being ignored.

As contributed by Brandon Kish

When configuring an LTI consumer, pass [custom_]record=true to indicate
whether the session should be recorded.

Save yourself hours of LTI debugging! Copying/pasting the URL bbb-conf
--salt brings along a trailing slash, which bbb-lti does NOT
appreciate. :)

I found that Blackboard prefers to send the Instructor role within the
"urn:lti:role:ims/lis/" URN. The support was already here, I just
extended the detected roles. Hooray for Blackboard support in
BigBlueButton!
