Minor: Displaying info tab in Plugin manager by default

[twMat]

Very minor:

Ctrlpanel > Plugins > ...to see the information tabs for a plugin.

TW plugin manager only default-displays an information tab if it is titled "readme" - not eg. "README" or "Readme" (latter is the case with TopStoryView).

Did I mention this is a minor point? No - oh, sorry, it is a minor point.
