[TASK] Add support for getting field's value from current template variables
[FEATURE] Add getFlexFormValues and getInheritanceTree methods to ConfigurationProviderInterface
[FEATURE] Flux variable sliding based on parentFieldName

This first phase allows simple, unconditional inheritance with merging of variables based on the inheritance tree. Also added is processing which strips off values which are unchanged in the local element, saving only the diff of inherited+local settings.

This means that in order to be fully restored, variables must also be retrieved by the ConfigurationProvider which then takes care of re-parsing the inheritance tree, merging variables to construct the proper full set of relevant variables.

[TASK] Remove type requirement from hook methods in TCEmain

This should allow 6.0 and 4.x to use the hook methods also on systems where the nasty class mapping bug is in effect. In this case, the solution appears to work - since the TCEmain hook class is not hooked up to an interface, it is possible to avoid a type requirement.
