Name via constructor

[supersaiyansubtlety]

• IdentifierPanel:
  • checks the nameability of the cursor's reference instead of its reference's entry in TableHelper; fixes Allow naming classes via their constructors #350
  • removes redundant inner/outer class checks when getting ClassEntry names; getName already return the simple same for inner classes and the full name for outer classes
• EditorPopupMenu:
  • accounts for cursor state in EditorPopupMenu::retranslateUi
  • checks the nameability of the cursor's reference instead of its reference's entry when setting toggleMappingItem's text; fixes the text always being "Mark as deobfuscated" for constructors; even when deobfuscated
