bashism removal patch

(I'm following the notes at http://www.tigase.org/content/how-help - although the bug reporter is dead (it looks like it's swapped to http://www.tigase.org/content/tigase-xmpp-server so I've raised two tickets there. It also seems better than a forum for bug reports, but I'll do as I'm told!)

This patch removes a pile of bashisms from shell scripts, it also has a few minor improvements:
- "$@" rather than $* (this copes with whitespace)
- tigase.sh works out TIGASE_HOME better and removes the bashism regexp at the expense of using readlink (which isn't in POSIX)

Cheers,

Adrian Bridgett
