Subject: [PATCH] Automatic conversion enum/int -  when mapping to class

Nette forms doesnt support data type Enum when mapping form values to class. This makes problems when using forms - see error reported here: https://forum.nette.org/cs/36594-prevod-vybraneho-optionu-v-selectu-na-enum-type

The fix isnt complicated and makes no BC break. The case is in more details discussed here: https://forum.nette.org/cs/36601-rfc-konverze-na-datovy-typ-enum-a-int-pri-mapovani-hodnot-formulare
