[gimp] Save the "lock-content" property on layers and channels in the XCF

[Michael Natterer <mitch src gnome org>]

commit 03d00c5e0f5dabb659d6c04d8d03c3de3aed33dd
Author: Michael Natterer <mitch gimp org>

    Save the "lock-content" property on layers and channels in the XCF
    
    Add XCF property PROP_LOCK_CONTENT and save/load it for all layers and
    channels. Vectors saving needs some refactoring here I'm afraid, so I
    ignored it for now.
