[TIMOB-12161] Android: Localization of string names with '.'

*Issue* It is known that the strings.xml file is less flexible in Android as it is used to generate the R.java file. (E.g. a build will fail if a string name starts with an integer or includes a '+', etc.) The above stated, if a string name includes a '.' character, a build will succeed but replace the '.' characters with '_'.

<?xml version="1.0" encoding="UTF-8"?>
<resources>
  <string name="my.value">Hello World</string>
</resources>

Since the replacement is silent, the dev is unaware of the change so the following will not work.

alert(L("my.value"});

*Temporary Work Around* For large code bases that cannot change the naming convention, the L function can be redefined, e.g.:

(function(object) {
  if (exports.osname ==="android") {
    object.L = function(lookup, defaults) {
     return  Ti.Locale.getString(lookup.replace(/\./g,"_"), defaults);
    };
  }
})(this);
