Source files with + in the filename have incorrect name field in file reference section(XCode 5)

[skeid21]

File names with + are required to be wrapped in quotes.

I've tested a change that adjust the construction of PBXFileReference to check for a "+". I also adjusted XCProject.GetFile to normalize the name passed in to include quotes.

Thanks. Actually I'm planning an update to support some new features of XCode 5, and this would help. Did you fork?

I did not fork; I tested on a local copy of the repo.
