use liam2/64 conda env to build the doc
update compile scripts
fixed running ViTables >= 2.1 via the view command
document workaround for cx_freeze/pyqt .ui handling clash
removed arch-specific build scripts

setting the env repeatedly always ends up messing up something, so it should really be done once and then build many times
update setup.py for ViTables 2.1 (and -hopefully- later)
