* Deletes the mmv.model.EmbedFileInfo class file and its test file
* Updates the extension.json and MultimediaViewerHooks.php files to reflect
these deletions (by removing entries from dependency lists)
* Refactors all instances of `new mmv.model.EmbedFileInfo()` to instead use a
POJO with appropriate properties. Conditional assignment is used for the
caption and alt properties if there is any chance they won't be available, to
keep from adding props with falsy values.
* Refactors JSDoc method annotations so that `@param` tags expecting an
EmbedFileInfo instance now expect an object; relevant properties of this
object and their types have been added to the method annotations as well.

* Removed deprecated testCount, which is no longer supported in this way.
It's only useful when wanting to explicitly expect 0 assertions (normally
considered an error).
* Replaced use of testCount = 0, with assert.expect( 0 ).

Also do a bunch of refactoring to:
* keep LESS rules in more sane locations so it is not as hard to get an overview
(most of the metadata panel rules were in mmv.less)
* move mmv.mixins.less up one directory as it is not specific to the UI
* move the SVG icons as all of them were related to the UI
* remove the marging-right hack which was used to keep the title text from
overflowing the button; instead use a float and overflow properties to make
sure text that is too long gets hidden
