Save current filter, sort column and display formats as a new view

Browse Source 
A new button is added to the Browse Data tab for saving the current display
of the table (current filter, sort column and display formats) as a new
view. This allows (specially for non advanced users) the creation of simple
views. It can be seen, either as a way of storing the current
filtering or as an easy way of creating views.

This reuses the query set in sqlitetablemodel, but the column aliases when
a display format is used has been changed from col%1 to the original column
names, i.e. format(`orig`) AS `orig`.
