<Swing Dev> [7] Review request for 7093156: NLS: Please change the mnemonic assignment system to avoid translation issue (Swing files)

[Alexander Scherbatiy]

bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7093156
webrev: http://cr.openjdk.java.net/~alexsch/7093156/webrev7.00/

  This is a request from the NLS team to backport the issue 7093156 to 
JDK 7.
  The original JDK 8 patch is rejected when it is applied to JDK 8 
because the property files are slightly different between JDK 7 and JDK 8.

  So the UIDefaults class is just copied to the JDK 7 and property files 
are regenerated.

  The properties from the following folders are updated:
    src/share/classes/com/sun/java/swing/plaf/gtk
    src/share/classes/com/sun/swing/internal/plaf

  According to the request from the NLS team the properties, mnemonics 
and mnemonic indexes are unified from the
    xxxText, xxxMnemonic and xxxMnemonicIndex to xxx.titleAndMnemonic 
(different patterns with the different suffixes are checked).

  The TextAndMnemonicHashMap class is added to the UIDefaults class that 
now parse requested keys and returns values from the unified properties.

Thanks,
Alexandr.
