8b16a71d50 Adds assert() for Nasal and fixes io.include internal marking 
- A simple assert() function is added to the globals namespace.

 - io.include() marks the target namespace to avoid dependency loops.
   If the namespace is marked before the script to be included is
   compiled, a parse error leaves the target namespace marked while
   the script has not been loaded. This patch fixes this problem.

6ae3fae393 Add io.include() function to Nasal base library 
io.inlude() loads and executes a Nasal file in place, effectively embedding
the script in the calling namespace. The function adds a symbol mark in the
namespace to avoid duplicate loading.

Additionally, in this path:

 + io.basename() & io.dirname(): Convenience functions for managing path
   strings. Designed after their unix counterparts.

 + string.normpath(): Improved support for relative paths. It can now handle
   paths starting with double dots, like ../../Directory

6662ba5006 Access checker: properly convert paths to the norm. 
The same was already done for fg-root and fg-home paths - it was only
missing for fg-scenery and fg-aircraft paths.

caca942012 revert last change: don't append cwd to relative paths for now. There's 
no way yet to safely detect absolute paths, so this would break on MS Windows.
This will only mean that relative paths will always fail, as they don't
match any pattern. These are all absolute.
