[R-SIG-Mac] two errors in Mac-GUI #import statements

[Cyrus Harmon]

Wow, talk about annoying... This took me an embarrassingly long time  
to figure out...

RController.m line 57 says:

#import "REngine/Rengine.m"

this should really be:

#import "REngine/REngine.m"

This makes no difference, until you go and compile on a case- 
sensitive HFS+ partition.

Similarly, line 32 in PackageInstaller.m should read:


#import "REngine/Rcallbacks.m"

not:

#import "REngine/RCallbacks.m"

(not the inconsistent use of StudlyCasing here).

Thanks,

Cyrus

p.s. the MacGUI rocks!
