typo in Adafruit_ST7735

[maqifrnswa]

examples fail to build because it can't find Adafruit_GFX.h

this pull fixes that

Which version of the IDE are you using? All the examples are compiling fine

[maqifrnswa]

Arduino version 1.0.5
avr-g++ (GCC) 4.7.2
avr-libc 1.8.0

uhm gcc 4.7.2 and avrlibc 1.8, these versions are not supported. Have you installed arduino from a package repository for your linux distro? Which distro is it?

[maqifrnswa]

I maintain the Debian package and try to report upcoming problems arduino
will face along with solutions (for example
#1448). This bug is not present in
the default download, but it is present in the default download if I use a
newer gcc.

Many are bugs in the libraries that don't show up in the current package
because the compiler isn't strict (yet). This is a problem that arduino
will have to deal with at some point as it moves to newer compilers and
newer hardware.

The severity of this is minor, or a "wishlist" item that would escalate
whenever arduino adopts a newer (or stricter) compiler. However, enough
users are using these libraries that if there is a typo (see below), it
should be fixed sooner than later.

More info:
TFT.h currently #includes "utility/Adafruit_GFX.h" and
"utility/Adafruit_ST7735.h" (that is correct) but utility/Adafruit_ST7735.h
#includes <Adafruit_GFX.h> (if not defined, so the question is why is every
other header file using "" but Adafruit_ST7735.h using <>, especially if it
places it outside of the search path for includes)

Maybe you can explain why it is in <> and I can patch it accordingly.
Thanks.

I see it has been fixed in the ide-1.5 branch, thank you!
