#277 Missing check for URL length in EditServiceImplementation

[John Davidson]

The function WriteAllowed() in EditServiceImplementation has a fixed length string where it should calculate the actual string length of the URL

Build 2.0.0.205 (SVN r947) Added a variable to hold the length of the URL where required in EditServiceImplementation.WriteAllowed()

Prior fix did not correct issue when using FwSync.

Made the check for DisableEditServiceWrite to be ahead of the check for MessagePost.aspx. When DisableEditServiceWrite is false in flexwiki.config FwSync (or any other tool) should always work. Check for MessagePost.aspx will only happen if DisableEditServiceWrite is set to true.

Build 2.0.0.209 (SVN r955) Properly implemented the url length check (WikiTalk and C# are not a good mix).
