KMyMoney: updated config for "Financial Times"

The URL for Financial Times has changed to: https://markets.ft.com/data/equities/tearsheet/summary?s=%1. This config uses Indentify by as Indentification number instead of Symbol.

It also requires a 3-character code at the end of each identifier. For example, for IBM, you would use IBM:NYQ. These can be found on https://markets.ft.com/data.
