Reorg folders for UI/Screen/Pages i

HI PB, I am working on devo10's GUI stuffs. After reading codes of the deviation repository and the deviation10 repository, I believe the deviation repo is much better than the deviation10. In addition, I notice that the deviation10 is not updated for over a months.
Hence ,I would like to start my work for the devo10 based on the deviation repo. I made a fork of the deviation and reorg some folders as I thought the GUI/Pages/Screen layers of the devo10 should be quite different from the devo8/6. Please check out the codes and let me know whether you are fine with the new folder structure and it is possible to have it merged back to the deviation repo.
Below are general desciption
a) Create devo10target, devo8target and devo6target folders inside the target folder, each of them has devoXX, emu_devoXX and common folders to hold files for real-device-specific, emulater-specific and common files
b) Move src/gui, src/pages and src/screens folders to under target/devo8target/common folder, which can be used for both devo8 and devo6 devices
c) Make a clone of the src/gui, src/pages, and src/screens and have them under target/devo10target/common folder. Interested parties can work on GUI stuffs for devo10 in these folders without interfere with the devo 8 GUI stuffs
d) Modify the Makefile and Makefile.inc accordingly. I tried the following make commands , all of them work on my Windows 7/8 and Mac OS environments
make
make TARGET=devo8
make TARGET=devo6
make TARGET=devo10
make TARGET=emu_devo8 WINDOWS=1 (Windows OS only)
make TARGET=emu_devo10 WINDOWS=1 (Windows OS only)
e) Move target_defs.h to the src folder as it is a common header for all devices. Also define LCD_WIDTH and LCD_HEIGHT based on the predifinition of target from the Makefile, in the future, we should used these 2 constants in all relevant codes instead of using hardcode of 320x240

The repo's url is : bitbucket.org/sunvsuv/deviationfor6810

I think this is good that you restructured, I was planning on doing something similar when I start the Devo 12 port.

I do agree with PB.

Maybe it is better to put gui into screen folder since the gui is also screen resolution related.

Thanks for above comments of both PB and xC. I now moved the screen back to under the src folder, and made minor change in the lcd_screen.c since devo10 could have a better performance LCD_Clear().
In terms of the gui folder, I don't believe devo10 could use any existing gui widgets because its' LCD has only black and white colors , hence can't support too much image-drawing, and properties such as OBJ_SET_TRANSPARENT()/OBJ_SET_MODAL. Though we can use "#ifdef devo10" to let the gui widgets be more flexible to different devo types, it will make the gui codes less readable and bug-prone to devo8, which is quite stable with PB's hard-working

Currently ,the emulator of devo10 is working properly without any hardcoding, I start to draw the main page and might have better thought about how to re-use devo8's gui codes. Your guys' comments and suggestions are highly appreciated

I'm not a developer, but I have read a little around er9x for Turnigy 9x.
And the display resolution and lcd looks close to Devo10.
Just an idea, could it be possible to reuse the Gui from er9x instead of rewriting it for devo10 ?
Remember I'm not a developer so take it as a simple noob question
