The rename functionality relies on deobfuscation for now - so let the user know
this and ask the user to enable deobfuscation to get rename working.

The "Force rewrite deobfuscation map file" option effectively disables
renaming, because renaming relies on deobfuscation map modification for now,
but Force rewrite rewrites the map on each file reload, destroying changes.
So. let the user know this issue instead of silent failure.

* Add getRealFullName() to ClassNode and JavaClass and searchJavaClassByRealName() to JadxWrapper

Those methods is like getFullName() and searchJavaClassByClassName(), but for class names without aliases.
It is necessary for renaming classes/methods/fields.

* core: Make getFieldNode(), getMethodNode() and getRoot() public

This is necessary for renaming functionality

* jadx-gui: Add Rename popup menu entry (renames classes, methods and fields)

It allows user to rename classes, methods and fields.
It updates deobfuscation map and reload file.
This may be suboptimal, and maybe some RenameVisitor should be added.
Deobfuscation should be enabled in order to allow this.
