[cdt-dev] ui change in fileListControl

[Alena Laskavaia <elaskavaia.cdt@xxxxxxxxx>]

FileListControl is widget that allows pick some list items and have toolbar on top with

small buttons like add, remove etc

I want to make few changes in UI

1) Change layout so button aligned to the end, right now they kind of the middle which is weird


​

Proposed change

​

2) That control when you press Add gives you fileselector (kind of) but it does not remember last selection, which is really annoying, so added code to remember last selection in dialog settings
