Coffice milestone 2

[Sebastian Sauer]

Aloha,

so you may have noticed that within last week(s) I landed a bunch of 
commits in a Calligra branch named "coffice".

Coffice (Calligra Office or coffee-in-office) is the try to get Calligra 
on to mobile. More concrete I target Android for now (BB10 and Sailfish 
would be the next candidates).

Goals are:
* Focus on a Calligra Words ODT viewer. Next step would be to add 
doc/docx support. Later Sheets and Stage.
* Slim! That means as small packages as possible. No huge +100MB packages.

Work done:
* kdelibs dependency got stripped out and Coffice is Qt only. For that I 
introduced a "fake" library that maps kdelibs 1:1 to Qt without all the 
functionality, daemons, etc. Most of kdelibs is not needed and those 
that is needed (KArchive only) was ported over.
* I decided to go with qmake rather then cmake. Reason is qmake works 
out of the box with all those Qt mobile SDK's out there,
* Most of libs links+compiles, textshape+variables+pictureshape plugins 
link+compile and Words itself linls+compiles.
* It links+compiles AND runs on my Galaxy Tab 2 Android 4.2.2 device and 
desktop.
* ODT documents are proper loaded and ddisplayed (pictureshape and 
variables disabled atm).

Work still to do:
* There where a few odd crashes but maybe I fixed most of them short 
before he commit. Needs more investigation and fixing if needed.
* While the renderer (render the view to an image and display the image) 
is threaded and it seems to work I did disable it for now (means not 
threaded yet). Needs more smoke-testing.
* Zooming (eg pinch-to-zoom) isn't done yet.
* UI is ugly, misses functionality, well its a pre-alpha release :)

To the results:
* I succeeded! :) Well, it compiles, links, runs, works and does the job.
* Also the Android package (and install size) of the result is *3* MB 
including everything but Qt (which is not part of the package). Now 
that's what I name slim and there is lots of room for future 
improvements. It should be possible to cut it down to half that size but 
3MB is already pretty good and so future trimming/slimming isn't my top 
priority,

Try yourself:
1. *THIS IS TESTING ONLY*
2, Please not distribute the link since I have limited traffic, Thanks :)
3. I will blog about that with the next milestone which I plan to 
publish as official first release in e.g. Google Play / f-droid.

p.s. to compile the code yourself you need to:
git checkout coffice
git apply coffice/Calligra-01.patchfile
cd coffice
qtcreator coffice.pro
setup, compile, test, give feedback and enjoy life :)
