FMSLogo Code

Fix a problem with the Simplified Chinese commander input where pressing the up arrow after pasting multiple lines of Logo code didn't move the insertion point, and so you couldn't get up to the commander input.

Rather than implement a LineUp() that emulates an up-arrow, I decided that the cleaner approach was to let the underlying control handler the up arrow however it sees fit. This works equally well for wxStyledTextCtrl and wxTextCtrl.

Implement CLogoCodeCtrl::GetCurrentLine for the Simplified Chinese version to fix a problem in the commander where pressing the up arrow after multiple lines had been pasted into the input would give focus to the command history, instead of scolling up within the command input.

Add support for File -> Print in the Simplified Chinese build of FMSLogo.
To do this, the PrintOut helper class and CLogoCodeCtrl::Print() implementations were refactored to be shared between both implementations of CLogoCodeCtrl with the only difference being FormatRange().

Implement the ReplaceAll functionality for the Simplified Chinese text editor.

Add an error message to configure-wxwidgets.sh when no parameter is given. This will help others who need to run the configure script.

Implement Search -> Replace in the Simplified Chinese editor

Add missing #include directives which prevented the code from compiling when precompiled headers are not used.

Fix a typo in the banner comment

Fix a bug in Simplified Chinese editor's "Find" functionality where, if the match included a chinese character (that is, a double-byte character), the match selection extended beyond the actual match.

Implement Search -> Find for the Simplified Chinese editor. To make this practically useful, this revision also makes the selection visible even when the editor does not have focus (otherwise you cannot see what was found).
