Fixed permissions on files.
Fixed some typos.

This are the typos from this pull request:
https://github.com/CaptTofu/DBD-mysql/pull/48
minus the Unicode problem in GetInfo.pm
plus removing trailing spaces
Update support information.

mysql.pm already pointed to dbi-users, README and INSTALL.pod pointed
to a not very active list on MySQL.com. I took the liberty of making it
consistent by means of pointing all to dbi-users.
Update github location.

I noticed some locations were already updated to point to perl5-dbi,
but mysql.pm still pointed at the old url.
