FMSLogo Code

Formally thank Pachleng for translating the FMSLogo GUI into Simplified Chinese, for being the first person to report on his experience with the HOWTO-BUILD.TXT, for assisting with the fix of the "half character" bug.

Stop ignoring wxfmslogo-*.exe. No installer by this name is built as of FMSLogo 7.0.0.

Formally thank Serio Adamo for reporting Bug #489 and for being among the first to work through the tests in the HOWTO-BUILD.TXT.

Note that bug #467 (the Chinese half-character bug) is fixed in FMSLogo 7.1.0.

Fix a potential source of confusion in the Simplified Chinese translation of FMSLogo where pasting text into the commander's input that happened to end in a newline looked like nothing was pasted (because all you would see is the final, blank newline). Now the text is trimmed when pasting, the same as the mainline version.

This change also revives similar functionality when compiled against wxWidgets 3.0.0 (as, for example on Fedora Core 25). In both cases, the ocde was copied from the 6.35.0 version.

Add some basic tests for Simplified Chinese.

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.
