build_and_install.sh: Offer fix when xcodebuild can't find Xcode.app.
If the Xcode command line tools were set to use a "command line tools instance", which can be installed without having Xcode installed, build_and_install.sh would fail. It prints an error message with a command that can fix it if you do have Xcode installed, but the message was kind of confusing and the command would fail if you didn't run it as root. build_and_install.sh now offers to run the command for you and then continues the installation. I've also tried to make the message a bit clearer and cleaned up some of the code. Also fixes another bug that occurred with this configuration problem, where the error from xcodebuild would be printed at an unintended (and confusing) point in the script. Fixes #108.
