WebAssembly: Improve browser selection combobox of run configuation

Browse Source 
This adds a "Default Browser" entry to the browser selection combobox in
WebAssembly' run configuration. Choosing that omits the "--browser"
parameter and let's emrun determine which browser to launch (should by
the system default browser).

In order to implement that, the combobox items now got user data in
addition to have display data. The parsing of emrun's output was
extended to retrieve the long form of a browser name as display data:
"Mozilla Firefox 96.0.0.8041" instead of just "firefox".
The parsing of emrun's outout received a dedicated plugin test.

Turning the result in parseEmrunOutput() non-static fixed
