FMSLogo Code

Fix a bug in CURRENTWORKINGDIRECTORY that broke under cygwin's bash

This revision changes the implementation of CURRENTWORKINGDIRECTORY to use DLLCALL for ::GetCurrentDirectoryA instead of invoking perl.exe as an external process. The problem with perl is that I had installed cygwin's perl and FMSLogo was finding it. This returned a cygwin path ("/cygdrive/c instead" of "c:\"), which caused the test code to fail to CHDIR back to that directory. As a result, running DIRECTORYTEST moved out of the "test" directory, which caused strange, difficult-to-understand downstream failures.

Since it's now possible to use DLLCALL to call get the working directory, it makes sense to do so.

Rename SEARCH_OPERATION_FindAndReplace to SEARCH_OPERATION_ReplaceAndFind.
This better relects the order in which the operations are executed.

Fix bug #500; Scroll any found selection into view when searching in editor.

Add some missing LOCAL to prevent leaking variables.

Fix Bug #499; When a single widget is added to a dialog or window from the setup instructionlist, it no longer fills the entire dialog/window.

This was a regression introduced in FMSLogo 7.0.0 caused by upgrading wxWidgets from 2.8.12 to 3.1.0. In this upgrade, there was a bug fix in wxWidgets that made it behave this way (that it, it was always supposed to do so, but it so happened than in 2.8.12 it didn't due to a bug).

The fix for the FMSLogo bug is to add a sizer to all wxDialog that are created with WINDOWCREATE or DIALOGCREATE. This disable the "single widget fills all space" behavior in wxWidgets.

Add a missing <parameter> tag for proper formatting of "instructionlist"

Fix some typos in the MIDIMESSAGE documentation.

Ban procedure documentation from starting with "This", as in
"This command does X". Instead a fragment "Does X" is preferred.

This was done for documentation-wide consistency.

Clarify what was meant by "The start position is always on the same ellipse, regardless of startangle".

When I read this recently, I couldn't understand what it meant or how the following sentence was explaining it. Instead of combining to unrelated ideas ("start position" and "same ellipse"), I removed the "same ellipse" explanation from the startangle description and added it as a conclusion to the inline/crosswise paragraph.
