Allow the use of newer versions of RichEdit

[dpradov]

KeyNote normally use the version of RichEdit included in C:\Windows\system32. That library is usually MSFTEDIT.DLL, if exists (with XP SP1 or later) or RICHED20.DLL.
It could be useful to be able to specify a particular version, specially if you have installed a recent version of Office, because they normally include a more actual or powerful version of RichEdit.

For example, if we have Office 2007, there will be a 6.0 version of RichEdit in the following folder:
C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE12
Note that recent versions of that RICHED20.DLL needs also the file MSPTLS.DLL

Some references:
