Merge branch 'feature/bug_678436' of https://github.com/albert-github/doxygen into albert-github-feature/bug_678436

Blank spaces after an if statement have to be removed as well. Also spaces before the firs round bracket have to be removed.

Blank spaces after an if statement have to be removed as well. Just enable them as part of the parameter of the conditional expression and remove them later on (to be safe not having them in the parser).

Chm don't add images multiple times

Enable Previous and Next buttons in chm output file

Superfluous < sign

Bug 726734 - alignment of blockquotes in pdf

Bug 726722 - Blockquote followed by text inserts an extra paragraph

Update doctokenizer.l

List only the project pages in "Related Pages"

Don 't add image to list in case it is already present (happened for image extsearch_flow.png in the doxygen manual).

Enables the Previous and Next buttons in case of a binary table of contents in the chm output file (binary toc is a requirement for the Precious and Next buttons).

Extension in config.xml if type=string with format=image

Removed superfluous < sign

The quote instead of quotation does align multi level block quotes

Remove superfluous \n from intermediate output.

This avoids cluttering "Related Pages" with links to pages from external
projects.

Added support for Subversion fixed-length keyword syntax (see: http://sourceforge.net/p/doxygen/discussion/130996/thread/1c641a9f/).

Removed ':' from the end of the section title for an RCS tag - it was inconsistent with sections created using other commands.
