Issue #216: Run current Robot test

[oeick]

By pressing F8 (default) the current Robot test will be started. "Current" means the test, where the (first) cursor of the active view is located.

By pressing Shift+F8 (default) the last run Robot test is repeated.

Configurable:

• optional: saving all open views when starting (or repeating) a Robot test
• folder for the log, output, report and debug files produced by Robot when using this feature
• optional (for Windows): keep console open, after test has finished
• set console width for console output when using this feature
• key bindings (default F8 and Shift+F8)

Thanks for the PR. Looked OK from the mobile screen and looked OK, but I definitely need to test and see the code from a bigger screen.
