Switch SolutionTable to TableView + TableViewModel [CPP-275]

[john-michaelburke]

Issues

• After talking with Qt it seems there is no way to create a delegate for creating new columns unless done in Python/C++ and even with that I'm not sure if it is possible to create a generic table widget as such. So I have tried to reduce the code for the table widget as much as possible but we will need to just copy pasta to other tables. 😢

Implements

• TableView with TableModel (new approach) for the SolutionTable.
  • ability to highlight a row and copy the data as a JSON.
  • ability resize column widths synced with the splitview.
  • dynamic creation of the headers using a hardcoded gradient for color.
• setup the tableview such that one function can be used for formatting all column and row data (could do for the headers if needed)
