Add the 'hocr_char_boxes' configuration option (off by default),
which enables printing the bounding boxes of each character in the
x_bboxes property of an ocrx_word element in hocr output.
Most command line programs print the version to stdout.
This seams to be reasonable for Tesseract, too.
Now a shell statement like "VERSION=$(tesseract --version)" works
without I/O redirection.

Takes advantage of inheritance and dir="ltr" default to:
- only generate paragraph dirs which are not ltr
- only generate word dirs which don't match enclosing paragraph
Tested against LTR, RTL, and mixed direction files. Files for the
latter two cases are in a separate commit on the ltr-test-files branch.
This fixes the duplicate line IDs caused by inserting height information
into the middle of the ID and it moves the line height info into
the title attribute like everything else, rather than using non-standard
HTML attributes (which won't validate).
This change may break consumers of the HTML output, but 3.04 has only
been in the wild for 6 months and the current HTML is invalid, so I
believe the benefit outweighs the cost for the fix.

The code in this commit solves the issue in a more elegant way, IMHO.
Now you can use:
* `tesseract eurotext.tif eurotext txt pdf`
* `tesseract eurotext.tif eurotext txt hocr`
* `tesseract eurotext.tif eurotext txt hocr pdf`
NOTE:
With `tesseract eurotext.tif eurotext`
or `tesseract eurotext.tif eurotext txt`
the psm will be set to '3', but...
With `tesseract eurotext.tif eurotext txt pdf`
or `tesseract eurotext.tif eurotext txt hocr`
the psm will be set to '1'.
Commit 99110df757 improved the help text
in several aspects, but also introduced new inconsistencies which this
patch tries to fix.
* Align columns (this needed replacing tabs by spaces).
* Start explaining text with uppercase.
* Replace "the stdout" by "stdout.
* Small changes in help text for page segmentation modes.
* Split options in OCR options and single options
(partially revert commit 99110df757).
In addition, whitespace characters at end of lines were removed.

Coverity bug reports:
CID 1270405: Uninitialized scalar variable
CID 1270408: Uninitialized scalar variable
CID 1270409: Uninitialized scalar variable
CID 1270410: Uninitialized scalar variable
Those variables are set conditionally in the while loop
and must keep their values in following iterations, so
they must be declared outside of the loop.

size_t is not always the same as long, especially not for 64 bit Windows:
api/pdfrenderer.cpp:549:31: warning:
format '%ld' expects argument of type 'long int',
but argument 4 has type 'size_t {aka long long unsigned int}' [-Wformat=]
size_t normally requires a format string "%zu", but this is unsupported
by Visual Studio, so use a type cast.
