feature request: make sticky properties

[GarryG]

As many probably use this tool to quickly find e.g. basic parts, or might want to allow for hand sodering thereby requiring 0402, 0603 or larger, it would be nice if one could select a preset of properties for the parts that does not change from search to search. Having to re-select the desired properties every time a search does not have the selected properties available is somewhat of a pain ...

I believe this is a duplicate of #40
