Modify AjaXplorer for speedup loading of folders with lots of files (>300)

Thanks to a tweet from AjaXplorer, now I can view with no problems the folder of my mobile pictures (about 500 files).

The secret stays in the PAGINATION_THRESHOLD parameter of bootstrap_repositories.php.

I changed this parameter from a value of 500 to 150 and now all works fine!

Thanks AjaXplorer stuff! 🙂
