Bug 56957 [Encoding] Reusable EncodingFieldEditor
I have added the ability to set an encoding for a repository so that commit messages and file names can be properly translated between a client and server whose encodings differ. I have extracted much of the code from IDEEditorsPreferencePage into an EncodingFieldEditor class so I could us it. I was planning on providing a patch to the UI with the hope that this class could be API but there is a roadblock that prevents this. Basically, the encoding preference is in a org.eclipse.core.Preferences node but a field editor requires an IPreferenceStore. There are already two adapters for this is the platform but one is a private inner class of AbstractUIPlugin and the other lives in the text plugin. Instead of creating a patch, I'm just attaching the EncodingFieldEditor class for future consideration.

			if (!file.exists()) {
				locationString += " " + FILE_NOT_EXIST_TEXT;  
			}
			return locationString;
		}
	}

				return MISSING_PATH_VARIABLE_TEXT;
			return NOT_EXIST_TEXT;
		} else {
			File localFile = location.toFile();
			if (localFile.exists()) {
				String bytesString = Long.toString(localFile.length());
				return MessageFormat.format(BYTES_LABEL,
						new Object[] { bytesString });
			}
