Update Howler to latest 1.1.25 version

see the Howler changelog for further details :
https://github.com/goldfire/howler.js/blob/master/CHANGELOG.md
[documentation] removed the class.Error documentation

this was kind of "polluting" the class list, and i would rather document
this through the Error class (by specifying that all end-user classes
are derivating from this one, and giving some example)
[documentation] improved documentation for the new `me.collision` API
[#545] removed the old jsdoc template
