Fixed some comments.
Fixed DcmSCPPool test case failing on older systems.
Enabled shutdown functionality of DcmSCPPool.

Finished implementation of DcmSCPPool::stopAfterCurrentAssociations().
Some basic tests have been run to ensure this method works as expected.
Fixed wrong tag in CodingSchemeIdentificationSequence.

Fixed wrong tag being used in CodingSchemeIdentificationSequence (0008,0110).
Instead of Responsible Organization (0010,2299) it should be Coding Scheme
Responsible Organization (0008,0116). This inconsistency was introduced back
in the year 2003 with CP-324. This commit also changes the name of the
corresponding get/set methods in class DSRCodingSchemeIdentificationList.
Fixed building with mingw-w64.

Renamed OFStandard::rand_r to OFrand_r to prevent collisions with
mingw's rand_r macro. Adjusted file position and offset data-types for
mingw-w64. Fixed some warnings caused by inconsistent inline-specifiers
in DcmTagKey.
Enhanced DCMTK CMake exports for external projects.

The files DCMTKConfig.cmake, DCMTKConfigVersion.cmake and
DCMTKTargets.cmake are exported by CMake to the DCMTK build tree as
as well as to the DCMTK installation directory. The files can be found
and evaluated by other CMake-based projects using CMake's find_package
command (in "Config" mode). The files describe DCMTK executables and
libraries as well as DCMTK version information, which then can be
facilitated in an automatic way by external projects to configure and
perform their own build process. Thanks to Jean-Christophe Fillion-Robin
from Kitware for the original patch.
Made installation of tag file optional.

Made installation of Doxygen tag file optional in order to avoid an error
message if it has not been generated, e.g. because "make html" was not called
before "make install".
Added another addContentItem() method.

Added new addContentItem() method that expects a pointer to a newly created
document tree node. This provides another approach of creating the document
tree of an SR document, and avoids making the detour using getCurrentItem().
Capitalized all CMake key words for consistency.
Ensure CMake v2.6 still writes DCMTKConfig.cmake.

The enhanced DCMTKConfig.cmake that was recently introduced relies on CMake
version 2.8.8 or higher and uses the new CONFIGURE_PACKAGE_CONFIG_FILE
command. This commit makes sure that older versions as the minimum CMake
version 2.6 required by DCMTK produce a DCMTKConfig.cmake that has at
least all the information it contained before the switch to
CONFIGURE_PACKAGE_CONFIG_FILE.
Replaced tabs by spaces and fixed indention.
DCMTK.cmake and DCMTKTargets.cmake documentation.
Added helpers to copy common modules between items.

Thanks to Andriy Fedorov for the original patch.
Fixed Makefile.dep for new files from last comit.
Switched windows line endings to unix line endings.
Added further module helpers and fixed small issues.

Added copy helpers for Clinical Trial Study/Series Modules, added missing
attribute in General Image Module and made code more consistent.
Fixed comments and error message.
Updated module helpers to latest DICOM 2013 draft.
Fixed various issues in Doxygen comments.
Fixed various minor issues in new helper class.
