Hide android server log

Hi,

I enjoy using Xfennec progress to monitor Android file transfers. However, there is a system transfer which can sometimes get in the way of the regular transfer progress. Can we please have an option to blocklist patterns like /private/var/folders/xc/*/T/adb.*.log?

It would require -i to accept a pattern instead of an individual file name. Open for contributions.
