This change makes the resource module use the new API when it embeds media
files (audio/video/Flash), and removes the resourcelib library functions
which were previously used for this.
The old API is still used for embedding non-media files such as PDFs and
HTML.
The URL and Lesson module both used copy/paste duplicates of a section of
resource module code which called the removed functions. I have changed
these too. As a bonus this significantly reduces the duplication involved.
New PARAM_COMPONENT, PARAM_AREA and PARAM_PLUGIN + fixing of hopefully all current incorrect parameter types. This should help with diagnosing of incorrectly named 3rd party plugins too.
Bug fixes:
* fixed broken flash resizing via URL
* upgraded Flowplayer
* fixed invalid context in format_text()
* all media related CSS moved from themes to filter and resources
* fixed automatic pdf resizing in resources
Changes:
* reworked filter_mediaplugin system settings - grouped by player type instead of individual extensions, added more information
* improved regex url matching
* removed old unused players, Eolas fix and UFO embedding
* image embedding moved to filter_urltolink
* new Flowplayer embedding API
* accessibility and compatibility tweaks in Flowplayer
* SWF embedding now works only in trusted texts, it is now enabled by default (works everywhere if "Allow EMBED and OBJECT tags" enabled)
* new default video width and height
New features:
* automatic Flash video resizing using information from video metadata
* Flash HD video support (*.f4v)
* Flash video embedding with HTML5 fallback - compatible with iOS and other mobile devices
* Vimeo embedding
* no-cookie YouTube site supported
* HTML 5 audio and video with multiple source URLs and QuickTime fallback
* more video and audio extensions in filelib.php
* MP3 player colours customisable via CSS in themes
* nomediaplugin class in a tag prevents media embedding
I added a deprecated method add_pretend_block that forwards to add_fake_block, so old code should be break. However, I aslo updated all the callers in core code.
Major tasks undertaken in this patch:
* New format_text argument, overflowdiv.
* New page layout Report.
* Review of all format_text calls.
* Added support for the report layout to all themes.
* Changed forum post display from tables to divs.
