* Made serialized data be saved as untranslated. To achieve this, added the
t_string class, which encapsulates a translatable string.
* Completely rewrote the (text) WML parser, making it use a tokenizer / parser
architecture. The parser is now much more strict and validates a WML grammar.
- Change to the WML syntax: pluses are now ignored, spaces are now forbidden
in WML keys
* Rewrote the way the variables are interpolated. There is no more default
interpolation, however, the vconfig class was added, which provides a
variable-interpolating proxy to config objects.
* There is still an important known bug: this is impossible to load textmode
save games now, because the statistics module saves some WML with spaces in
keys, which the parser refuses. I am commiting anyway to respect the string
freeze; the fix for this bug will come tomorrow
Hoping I do not break everything...
