i18n 1.053 released

optimized the mysql modus. now a new column "namespace" is used to speed up things a little bit. if you use that modus you have to add that column to the translation table. see the documentation how that namespace thing works.
Also the way the INI file is read has been changed. instead of reading it everytime an object is created, it will only be read once per page and stored in a global variable
