#104 Symbols in UTF-8 aren't saved correctly to MySQL by default

Non-latin symbols entered in XPlanner aren't saved correctly into MySQL database, even if MySQL database was created with default character set utf8. By some reason this issue doesn't affect local XPlanner+ installed on Windows, but it appears when XPlanner+ is installed on Linux. The source of the problem is Hibernate and this issue could be fixed by setting:

hibernate.connection.url=jdbc:mysql://localhost/building_xplanner?useUnicode=true&characterEncoding=UTF-8

in xplanner-custom.properties file.

I suggest either change this setting in xplanner-custom.properties file or add appropriate comment to the instruction "Installing XPlanner+"
