Bug 729236 - Added HIDE_COMPOUND_REFERENCE config option
Bug 700510 - Bibliography duplicate filenames fails

Problem in the bug report is that the bib files in the different directories have the same name and thus overwrite each other.
This patch solves this problem as well as the possibility to have spaces in the file name.
For all output formats the bib files are copied to a new numbered name: "bibTmpFile_<number>", for Latex on the LATEX_OUTPUT directory and for all other formats in the subdirectory "bibTmpDir" of the OUTPUT_DIRECTORY.
The files for Latex are retained whilst the files for the other formats are removed after usage (as it was before).

Support multiple extra HTML stylesheets.

In regular use it happens that it is more convenient to have multiple extra HTML stylesheets, e.g. in case of different levels of requirements: company, department, project
With this patch it is possible to specify multiple HTML stylesheets.
Note: for compatibility the configuration parameter HTML_EXTRA_STYLESHEET has not been renamed to HTM_EXTRA_STYLESHEETS.
Create an easy possibility to take a snippet from the current file.

In case the snippet of code is in the current file one has to specify the name of the file and also see to it that the file is reachable through the EXAMPLE_PATH.
A use case is the case of a list of initial values here it is quite often more convenient to have the values listed in a 'nice' list than direct in the definition line.
With this patch it is possible to specify the name of the file where the snippet resides as: this
