Checks shell paths to see if they exist and can be executed before showing them in the quick pick dropdown (#2).

@Tyriar Relative paths not working for me anymore after 5ca536d (Windows)

[Tyriar]

@chentel what are the path's relative to? Workspace root?

[chentel]

@Tyriar in config settings

works:
{ "shell": "C:\\Windows\\System32\\bash.exe", "label": "WSL Bash" }

no longer works and shells not added to pick list:
{ "shell": "bash.exe", "label": "WSL Bash" }

Oh items in your path, good point. Will fix up now
