[Gui] Program selection using a tableView

[LucBerge]

Is your feature request related to a problem? Please describe.
The current program selection uses dropdown lists, pograms are referenced by Place, Category, Subcategory and Titles. In this way, we cannot get a clear overview of all the programs making the program selection complicated.

Describe the solution you'd like
The idea would be to have a tableView with all the programs in it just like in the "Person" panel. The table has 4 rows : Category, Subcategory, Location and a title with possibility to add filter for each column to make a program searchable. Each program also have a short description which is displayed next to the table when seleted.
