fixes #11

@BenWildeman Works well. Only thing is that default terminals without commands are "blank" when first opened and need any input to actually show. This can be "fixed" by sending a blank command after creation :

if (command) {
    _terminal.sendCommand(command, executeCommand);
} else {
    _terminal.sendCommand('');
}

in common -> loadTerminals

This is a bug with VS Code itself, and seems to depend on which terminal you use. for instance, I use powershell v6 and it doesn't do this (regular powershell it does). however, I will add this as a setting instead of just assuming it's required for everyone :)

just looked into the issue above, it's a windows 10 specific issue that was fixed and landed in windows build 1903 so I will not be adding in a feature to circumvent this

(I updated to powershell v6 around the same time of updating windows, hence why I thought it was a specific terminal issue)

Well, the update still haven't landed on LTSC, but it's not the end of the world and I can just use a default command of "ps" or "ls" or something in the meantime. Edit: just a space command works well as a workaround.
