[info kcm]: add vendorinfo card
This change adds a card to the Information KCM which can be used to display vendor-specific information (think of product info, serial or model number, support info, etc.).
The information is read from a json file in /etc/vendorinfo.json, format as follows:
''' { "Title" : "Vendor Information", "Content" : [ { "Key": "Model Number", "Value": "24ABC-13N4" }, { "Key": "Serial Number", "Value": "778899223344" }, { "Key": "Support Phone", "Value": "+31 6 48370928" } ] } '''
Title is the card header, each Key/Value block adds a TextDelegate. This block is only displayed if the file actually exists and has a Title set.
