data: Added HeaderSearchPaths to Application- and ProjectSettings

This change allows for parsing of a real codebase by specifying the system header search paths in
ApplicationSettings.xml and the additional header search paths in ProjectSettings.xml.

Both settings files are now documented in ApplicationSettings_template.xml and ProjectSettings_template.xml, which show
all possible settings for each file.

This change also fixes some parsing edge cases that occured.
