#11 make IE's 'default' security levels stricter

[Pete Boyd]

set the 'default' to something high so that if people
need to use IE they can just click a button in the
Security tab to go to our recommended level

use the 'RecomendedLevel' registry key:
0x00010000 Low Security
0x00010500 Medium Low Security
0x00011000 Medium Security
0x00012000 High Security
