change stats.radata file

[resession]

fs.writeFile(__dirname+'/../stats.'+(root.opt.file || file), raw, function(err){ W = false; err && console.log(console.STAT.err = err); console.STAT && console.STAT(S, +new Date - S, 'stats stash') });

the above line is what creates the following error:
Error: ENOENT: no such file or directory, open 'C:\Project\gundb\tests\node_modules\gun\stats.C:\Project\gundb\testingFolder'

does the stats.radata need to be the root.opt.file? because if someone inputs a file directory like C:\some\path\here, it will make the stats file into 'stats.C:\some\path\here' which i think is the problem for fs.write functions. what i did is create the stats.radata file only in the gun directory, tested it and i get no errors now. will this be satisfactory?

[resession]

it tries to create a file called "stats.C:\Project\gundb\testingFolder", that is why fs.writeFile is having issues, that is not a valid filename. so i changed it to "stats.radata"

@resession excellent! This is actually how it worked originally, but it caused problems when running the PANIC tests (or any time someone runs 2 versions of GUN on the same machine).

2 versions of GUN started in the same directory will both attempt to write to the same 1 database file/folder, which breaks/crashes stuff. The same "clobbering" happens for the stats system.

So to launch 2 versions of GUN (which PANIC does for testing multi-peer setups), peer 1 Alice needs to call herself GUN({file: "alice" and peer 2 needs to call herself GUN({file: "bob"

The stats data is not important tho, so I can accept this PR as-is, but would you be willing to modify it slightly further? If you want the data in a separate directory, maybe the stats data should be saved to ../stats relative to the provided path? Or maybe still keep saving it to the gun folder but just do an .split('/').slice(-1)[0] so it uses the last path name to prevent the alice vs bob collision?

THANK YOU SO MUCH FOR HELPING WITH THIS!!!! <3 <3 <3

does the new change work? i brought in the path module to use path.resolve. in case someone uses a literal '\' separator(which will throw off the .split('/')). also using path.sep, that way we are using the os's separator. if opt.file has not been passed in, then we will use 'radata' by default.

i chose to save the stats file in the gun folder, reason being is i think gun related things should stay close to the gun folder itself. tested this, works good.

thanks for the good words, love seeing gundb and projects like it
