Random file name length

[vvrein]

Hi! Thank you for maintaining linx!
I thought it would be nice to have parameter for setting file name length for files uploaded with Linx-Randomize: yes.
Like a set it to 30 and get names like this ouAgN06Plt9MdKoUCt9p9uabT9U1tZ.md instead of y0kkytts.md.
Thanks!

I would like to shorten it to 5 characters.
