Remote file duplication

[wizzard]

Rempte file duplicates, when simultaneously altering the same remote file from local synced folders, steps to reproduce:

• start two megacli instances, sync the same remote folder to two local folders
• in each local synced folder simultaneously write to the same file
• remotely two files appear with the same name

If my comment can help : this issue will also be applicable for two instances running over the network, a simple lock mechanism in the sync application will not help.
I can see two potential solutions for that :

• Creating a merged file remotely - this is not that simple as this would require automated file edition thus altering user content -
• or keeping the two files remotely with an addition of a "conflict" flag - probably in the file name itself - to avoid confusion and keep the content as-is, the two copies will then be available remotely and locally

Addition to this issue: I noticed that sometimes on Windows, when remotly I have duplicated files, megacli starts infinite sync loop:

Reproduced remote folder duplication on Windows. Basically I just created a folder and filled it with the files. Then opened Web interface and got the following picture:

At that time Mega servers were definitely lagging alot, were contantly getting "retry" messages in megacli console.
