[FEATURE] Decoupled WidgetController from t3lib_Singleton

...goes without saying that this enables a much more transparent
approach when working with multiple Widgets of the same type and trying
to use $this->widgetConfiguration to store values which are unique to
the current ViewHelper only (instead of bleeding through to all Widgets
of the same type with the last Widget overruling all).
[BUGFIX] Removed another trace of FED

Removed usage of fed:swtich. Symptoms to error: double link output when
FED is not installed due to unconditioned output of two possible
display modes.
[TASK] Adapt Uri/Link ViewHelpers to new Widget base

Adjustment to allow passing of tag content as argument as well as tag
content, better support for inline usage.
[TASK] Remove Bootstrap resources

If anybody wants these included, it's better to grab them from the
source.
