Must only be called during an opt/initialise hook
Adds a page to the options dialog
wParam = addInfo

addInfo must have come straight from the wParam of opt/initialise
Pages in the options dialog operate just like pages in property sheets. See the
Microsoft documentation for details on how they operate.
Strings in the structure can be released as soon as the service returns, but
icons must be kept around. This is not a problem if you're loading them from a
resource.
Prior to v0.1.2.1 the options dialog would resize to fit the largest page, but
since then it is fixed in size. The largest page that fits neatly is 314x240
DLUs.
