Fix: MySQL version to check fails with server versions > 9

The version check for the MySQL server version in the install routine
tries uses string comparison, which fails for version numbers with more
than one digit.
Changed to parsing the MySQL version as float and then comparing against a
number.
Fix: Remove size attributes from Corp descriptions

The size attributes in Corp descriptions are interpreted differently in
HTML as they are ingame. This lead to huge fonts for corp descriptions in
the browser.
Size attributes are now removed completely from corp descriptions.
Enhancement: Added parsing of showinfo-links in corp descriptions

Added parsing of showinfo-links in corp description for entity types Corp,
Alliance and Pilot. Showinfo links to such entities in corp descriptions
will be replaced by links to that entity on the killboard
(corp/alliance/pilot detail page).
Feature: Show DNA ship fitting for kills in IGB

When viewing a kill with the IGB there's now an option to display the
fitting as DNA fitting in the client (and save for to the
personal/corporation fittings).
Thanks for this patch to tinducan!
