Tracer v1.1.7 breaks when fontconfig is upgraded

[amilesj]

I installed BEAST2 v2.5.0 via conda, which upgraded fontconfig from v2.12.1 to v2.13.1. After this, I tried to open Tracer v1.1.7, and it threw the following error:

java: symbol lookup error: /gpfs/home/amiles/miniconda3/jre/lib/amd64/../../../lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

When I downgraded back to BEAST2 v2.4.5 and fontconfig v2.12.1, Tracer worked again.
