feat: Display VPL remaining time and free evals + resizable evals results + memorize evals + vplignore

On the top of the vpl view, the time remaining before the vpl ends (if set up) and the number of free evaluations remaining, cost of extra evaluations and number of already lost points are displayed. The result of the last evaluation is now stored so that it won't be lost after changing project or quitting eclipse. Also, the separation between the tests tree and the evaluation comment in the result tab is now adjustable. In addition, a file vplignore is now generated in .settings based on a template which lists all files that should be excluded from pushes and evaluations.
