[CLI parser] mtouch arguments are not escaped properly

[dodikk]

Some parameters may have spaces and specific symbols. For example, we have a device named "Igor’s iPad". The tests are not launched properly on it.

Steps :

1. Rename your device to "Igor’s iPad"

2. Install a test app on it

3. Try launching it with TouchServer

mono Touch.Server.exe \
  --verbose           \
  --autoexit          \
  --port=16393        \
  --launchdev="your.app.bundle" \
  --devname="Igor’s iPad" \
  --logfile=UnitTestReport-Device-iOS8.xml

Actual result :
The script hangs because of an unescaped input (see the log below)
