ToxAlerts: Alert substitution variables

The list of variables you can use in your SMARTS patterns
ToxAlerts allows to substitute complex sub-patterns in SMARTS with simpler and more interpretable variables.
For example, instead of [CH1]([F,Cl,Br,I])([F,Cl,Br,I])[CH2][CH3] you could use [CH1]([$Hal])([$Hal])[CH2][CH3]
