MAINT: revise PR 68

* the new bash "if" block for weekly
wheels uploads has been adjusted to
remove comments from inside the block
& place them before, which seems to
help the syntax parser

* miniconda is installed so that
"conda" command may be used

* the version of miniconda is now
conditioned on platform & 32- vs.
64-bit arch
