Relocated files for SWI-Prolog Pack release.
Several small changes while preparing for the Weblog Prolog Pack.

* In debug mode include the ANSI module for colorization in the terminal.
* The load file used to assert the search paths relative to the pwd from which swipl was loaded.
* File loading for the weblog demo is updated to reflect the new directory structure. (Two demo files do not exist yet, commented out and added the @tbd tag.)
* Autocompletion file was not UTF-8 encoded like the rest. Changed the encoding to UTF-8 and added an explicit encoding directice.
* `gmap`, `leafletmap`, and `resources` would throw errors when their key files were not present. The situation in which these files are missing is now explicitly identified and can be acted upon accordingly. Currently we display a warning message to user output.
Included Prolog Pack file.

Cleaning up directions for release
* Use load_settings/1 for loading settings files. Settings are defined with setting/4 in the modules where they are used. The setting files contain setting/2 facts.
* Added gitignore file.
* Added explicit module imports in debug file.
* Removed unused settings loading in resources.
* Added module indicators to settings in settings files.
* Removed superfluous assertion of file search paths.
* Added explicit module imports.
* [GMAP] Updated from Google Map API v2 to v3 (v2 was deprecated in 2010 and v2 requests will served via the v3 API as of 2013/11; migrating before the latter date is advised by Google).
* [GMAP] Use URI library for creating URIs out of basic components.
