WEB2PY_MIN branch will never execute

[wolfmanstout]

The following lines look like an attempt to have the WEB2PY_MIN branch execute by default:

OZtree-docker/Dockerfile

Lines 35 to 36 in 252f6ad

	ENV WEB2PY_MIN=1
	RUN if [ "${WEB2PY_MIN}" == true ]; then \

This Bash syntax is a string comparison, so "1" won't be equal to "true". Looking at other usages of WEB2PY_MIN, this is the only instance where it is set to a number, so the simplest would be to change to ENV WEB2PY_MIN=true.

Alternatively, if a numeric flag is preferred, you could use the following Bash syntax:
if (( WEB2PY_MIN )); then

You would also need to change all instances of this variable to 0 or 1.
