FMSLogo Code

Add some missing NOT_YET_LOCALIZED tags to the strings in the About FMSLogo that have not been translated to German.

Make the link to NSIS's homepage clickable in the About box.

Move the "Core by Brian Harvey" into a panel.
Although this doesn't make much difference for Windows, this puts the same border as the other "about box" panels for GNU/Linux.

Fix CenterableLink to center on GNU/Linux.
On GTK, the wxHyperlinkCtrl is larger than the link text.

Fix a build-break on GNU/Linux caused by using wxHypertextLinkCtrl

Make the link to softronix.com clickable in the About box.

Implement Feature Request #91; The link to the NMSS is now clickable.
This is a promise I had made to George Mills many years ago.

Move CCenterableLink into its own header/source file.
This was done so that it can be used by aboutmultiplesclerosis.cpp.

Make the link to FMSLogo's project page clickable in "About -> FMSLogo..."
This change sets the pattern that will be applied to the other links.

Fix Bug #564; Tree recursive procedures with no base case one again throw an "out of memory" error, instead of causing FMSLogo to exit.

This fix restores the original strategy for out-of-memory that existed in FMSLogo 6.29.1, which is to allocate a reserve to be used when malloc() fails for the purpose of returning things back to normal.

This fix isn't perfect, as attempts to select "File -> Load..." after running out of memory cause FMSLogo to disappear. However, unlike bug #564, this is NOT a regression and so is likely due to some other problem.
