"Target Forward" and "Target Back" actions must always be available

[Laraul]

This should be fixed... until then you can add the following Macros.
.
Target Back
/micon "Target Back" General
/previoustarget

Target Next
/micon "Target Forward" General
/nexttarget

These should not display the "Can't not use while casting" error when clicked/triggered. Add these to there proper place so your hotbar and use them as you would have the standard "Target Back" and "Target Forward" buttons.
