Doc update from Devin.

Here's what I've changed:

changes to the doc htm files:
- added open definition
-> added concepts/cdt_c_open_definitions.htm
-> added images/openDefinition.png
-> added images/open_definition_error.png
-> updated images/openDeclaration.png
-> updated images/open_declaration_error.png
-> added tasks/cdt_t_open_definitions.htm
-> updated links to point to open definition wherever open declaration is linked
- information about the code reader buffer and properties in the menu
-> added images/cdt_pref_parser.png
-> added reference/cdt_o_parser_pref.htm (C/C++ Parser preferences)
-> added reference/cdt_u_c_parser_codereader_cache_pref.htm
-> added link to cdt_o_parser_pref.htm in reference/cdt_o_ref.htm
- removed reference/cdt_u_shared_lib_view_pref.htm since it has no useful information (also removed the corresponding link in contexts_CDT_DEBUGGER.xml)
- renamed the link absolute path "file:///E:/CDT/3.1/eclipse/org.eclipse.cdt.doc.user/images/indexer_import_largeproject1.PNG" in
tasks/indexer_importing_large_project.html to the relative path "../images/indexer_import_largeproject1.PNG"
