Do not use any inline style or javascript anymore.
Instead js logic is moved to js file.
Information are passed via data attributes.
Some options are not respected anymore. That's why this change is
breaking. Those options can be considered as obsolete anyway for current
state of the art.
Those options are:
TSConfig:
* options.feedit.popupWidth
* options.feedit.popupHeight
TypoScript:
* stdWrap.editIcons.styleAttribute
Resolves: #5
