[MonoDevelop] A simple bug of the Web Application project template (MD trunk)

[Matt Guo]

To reproduce, with MD built from latest trunk code (r152812)

Create a Web Application project named "WebApp1", press Ctrl + F5 to run:

Error CS0016: Could not write to file `bin/WebApp1.dll', cause: Could
not find a part of the path
"/home/matt/Projects/WebApp1/bin/WebApp1.dll". (CS0016) (WebApp1)

Sounds like the building shall create a bin folder if it doesn't exist.
