Don't unescape XLIFF tags on Android

Problem: 
  * On android XLIFF tags inside of a string should not be escaped. (See [here](http://developer.android.com/distribute/googleplay/publish/localizing.html#strings)).

Solution: 
  * Unescape XLIFF tags using Regexp.

Test: 
  * Site: http://gskinner.com/RegExr/ 
  * Match: ``(<xliff[^>]*?)\\"([^>]*?)\\"([^>]*?>)``

  * Replace: ``$1"$2"$3``
  * In: ``TEST " (<xliff:g abc=\"test1\" def=\"test2\">\"%1$s\"</xliff:g> <font color=\"red\">TEST</font>/ ""<xliff:g ghi=\"test3\">%2$s</xliff:g>) ""`` 
  * Append the output in the input box until no changes are happening:

```
TEST " (<xliff:g abc=\"test1\" def=\"test2\">\"%1$s\"</xliff:g> <font color=\"red\">TEST</font>/ ""<xliff:g ghi=\"test3\">%2$s</xliff:g>) ""

TEST " (<xliff:g abc="test1" def=\"test2\">\"%1$s\"</xliff:g> <font color=\"red\">TEST</font>/ ""<xliff:g ghi="test3">%2$s</xliff:g>) ""

TEST " (<xliff:g abc="test1" def="test2">\"%1$s\"</xliff:g> <font color=\"red\">TEST</font>/ ""<xliff:g ghi="test3">%2$s</xliff:g>) ""
```
