Make live edit cycle more smooth

[GoogleCodeExporter]

In v. 0.2.2 live editing is not highly usable. 2 issues slow down the work:

1. "Push" actions is not easily accessible. One has to open context menu, then 
a submenu and choose a menu element, which is quite slow. A shortcut or even 
auto-push (push simply on a file save, perhaps with confirmation box) would 
make the feature a way more convenient.

2. Files under a virtual project are all read-only by default. User has to 
explicitly drop this attribute again and again after each live edit push. It 
would be nice to spare him from this.
