Enhance annotation symbol substitution to include non-text symbols.

    Annotations can often include non-text symbols such as an interstate number in an interstate symbol or PLSS related numbers in ovals or circles. Currently symbol substition only allows the text to be changed so the symbol needs to be edited anytime you want it to look different. This makes it near impossible to have annotation be customized in different maps at the same time. Symbol substituion was introduced because there is a need to customize annotation without always editing, so it is a logical extension to include non-text symbols that are part of annotation.
