[Tclplugin-core] persist feature

[Wojciech K. <woj...@ko...>]

Hello.

I've been wondering about potential attacks on the host system using 
persist feature. The thing that looks like a small flaw is that 
directory name can be guessed (ie C:/Documents.../user/.../dir%d) - it 
looks like it's impossible to use it, but ... it'd still be better to 
protect it against guessing.

For example using a 8bytes random characters directory name (this will 
give 2^48 possibilities to check when using base64 charset) will make it 
almost impossible to find the desired file.

I'm a bit paranoid, but it doesn't hurt :)
