[REF] im_livechat, mail, website_livechat: clean mail model folder

The utility classes `Timer`, `Timers` and `CCThrottleFunction`
were only used by the feature 'is typing...', thus all those files
were in the same folder.

This commit moves the utility classes in a dedicated folder,
and introduces a folder for thread mixins, in preparation for
future features on threads that will be implemented as mixins.
