7af786fde9 Added a nice UI for the E2E-enabled account first connect 
Instead of immediately popping up the mnemonic dialogue,
only show a notification bar on the account setup page.

For the cases where the user does not want to use E2E,
this is significantly less intrusive than the old approach.

d3b6aacf3f Fix merging remote and local trees when e2e files are involved 
When populating the tree from the filesystem we need to fill
the e2eMangledName from DB and we when trying to find another
match on the oposite tree we need to take in account that names
don't match and search with the mangled name information

If the metadata is empty we should store (and not update). 
Android only creates the metadata file when the first encrypted file is
added. We assumed it would be there.

This hacky code makes us store the metadata if there wasn't any yet.

No sharing in metadata yet and PEM as PKCS#8 
* Don't store the metadata yet this crashes android
  - Yes android should be fixed but for now this is quicker ;)
* QSslKey exports PEM as PKCS#1
  - This is not handled properly on android so use PKCS#8 helper

Salt should not be hardcoded 
We append the salt (just like the IV) to the ciphertext of the private
key. This means we also have to split it off properly.

This breaks compartibility with currently stored keys on your server.
