messages are displayed in the browser (with locales)
changed: MountParser
         now if there is an error in a line -- the line is simply skipped

+	session logger
+
+	sample:
+	#include "log.h" (or slog.h)
+	slog << logerror << "message" << "something" << logend;
+	slog << logwarning << T("message_to_translate") << x << logend;
+
+	if the latter example "message_to_translate" will be taken from locales
+	currently following manipulators are taken into account:
+		loginfo    - the message in a normal info
+		logwarning - this is a warning
+		logerror   - this is an error
+		logend     - end of a line -- we have one kind of a message (info, warning, error) per line
+
+	loginfo, logwarning, logerror should be specified at the beginning of a line
+	(other manipulators are skipped)
