Improve controls option

[mitfik]

After placing control user needs to visit options to define basic properties.

Those options will generate proper overlays at the end.

Label -> Label Overlay
Control Type -> Schema base -> attr type
Name -> Schema base -> attr name
Default Value -> Entry Overlay
PII (checkbox) -> Schema base -> pii_attributes
language -> Apply language for all overlays create for that attribute
Information -> Information Overlay
Format -> Format Overlay
Encode -> Encode Overlay
Review (checkbox) -> Review Overlay
Source (checkbox) -> Source Overlay

All other properties available in the tool are not relevant for the ODCA and should be remove (see presentation layer for more details #12 )
