gISOmount should run as user

Hey all.

Uhh, gISOmount should run as a user, not as root.

It is very dangerous (and highly inconvenient) for certain desktop applications such as X-Chat or gISOMount (that is, desktop applications which are not intended to access data from the root user) to run as root, because:

* if (as an example) X-Chat is always running as root, then there is a settings/configuration problem pertaining to multiple users. See your bookmarking feature - it probably saves the bookmarks in $HOME. the root user's $HOME is /root, which leads us to the next problem...
* if the user wants to save a file in *their* home directory, well too bad so sad - THEY CAN'T. This is the gist of the "settings/configuration problem" that I mentioned above.
* and finally... What if the user was "stupid" (so to speak) and downloaded a different third-party gISOMount that could be a trojan horse to various exploits/etc???

Please take your time to consider this.
