Sort and autoformat xml inside .edmx files before saving via EF Designer
Need the EF designer to generate nodes inside .edmx file in exactly the same order they are present in the database (currently a list of entity properties is saved in reverse order in mappings section, also when you update the model from the database schema the ordering is messed up). Also before saving .edmx file EF Designer should auto format the document. This would help significantly with branching, merging and resolving conflicts during merge operations of .edmx files.
Steps to reproduce: (1) Generate EF data model based on an existing database (2) Add a couple of new columns, indexes, foreign keys (3) Regenerate the model based on the updated db schema (4) Open .edmx in XML editor and check that for example a list of property nodes is no longer sorted as it should be also sorting differs in model, store and mapping sections.
