Issue looking for GitHub app when running

[bejayoharen]

I have recently updated to revel 1.0, and my colleague pulled the changes. However, when it came time to run it, things got weird:

$ revel run -a .
Revel executing: run a Revel application
Changed detected, recompiling
Parsing packages, (may require download if not cached)...ERROR 15:57:14 harness.go:239: Build detected an error                   error="lstat /Applications/GitHub.app: no such file or directory"
panic: opps
goroutine 31 [running]:
github.com/revel/cmd/utils.(*SourceError).Error(0x0, 0x15bedda, 0x17)

we eventually resolved this by using the GitHub Desktop app, and the following commands:

$ mkdir /Applications/GitHub.app/
$ mkdir /Applications/GitHub.app/Contents/
$ mkdir /Applications/GitHub.app/Contents/Resources/
$ cp -r /Applications/GitHub\ Desktop.app/Contents/Resources/app/git /Applications/GitHub.app/Contents/Resources/git

I don't know how to reproduce, since it doesn't happen on my machine, but it seems like a bug that revel is expecting expecting to find /Applications/GitHub.app, and I'm hoping that's useful to you even without more info.

The opps error indicates a Error was call on a nil error object Which was done in this bad line of code
revel/cmd#210 fixes the error
