fixed cmd parser when arg is like -+
Added proper testing of the end of quicktime video files.

CvCaptureFile::grabFrame() always returns 1 regardless, which causes
dead loop when relying on the return value of VideoCapture::read().
Removed trailing whitespace in cap_qtkit.mm.
Fix ocl::calcHarris not support CV_32FC1 bug.
A minor fix.
Fix merge conflicts
Fix the whitespace warning.
Fix the build of OpenCV with XIMEA on Windows 64 bits:
  - crosses initializations in "cap_ximea.cpp" (which also contained some awfull "goto" instructions)
  - the "CMAKE_CL_64" variable is not initialized when using mingw

PR#1039 modified to be able to merge on branch 2.4
Trailing whitespace removal.
Using four spaces for indentation.
minX1 should be max(-maxD,0) not max(maxD,0), avoid black band at left
Reworked documentation building to work with extra modules.

The main problem with extra modules is that they're located outside
of the OpenCV root, while Sphinx requires that all documents are
within the documentation root. To circumvent this, we create a
"fake root" and copy all documentation (as well as all files that
it depends on) there. It's a bit messy, but what can you do.

As a bonus, this eliminates the need to generate modules/refman.rst
inside the source tree.

Made the generated file templates' naming more consistent.

The general convention is <output file name> + ".in".
