IMEx modules are not working

[tschaka1904]

This relates to #4

This is the maven output:
Failed to execute goal on project jami-imexcentral: Could not resolve dependencies for project psidev.psi.mi.jami.bridges:jami-imexcentral:jar:3.0.2-SNAPSHOT: Failed to collect dependencies at edu.ucla.mbi.imex:icentral-api:jar:2.0: Failed to read artifact descriptor for edu.ucla.mbi.imex:icentral-api:jar:2.0: Failure to find edu.ucla.mbi.imex:imexcentral-project:pom:1.0-SNAPSHOT in http://www.ebi.ac.uk/intact/maven/nexus/content/repositories/imex-public was cached in the local repository, resolution will not be reattempted until the update interval of imex-repo has elapsed or updates are forced -> [Help 1]

edu.ucla.mbi.imex:icentral-api:jar:2.0 has a parent which is edu.ucla.mbi.imex:imexcentral-project:pom:1.0-SNAPSHOT. But we can't find the parent.

For now, I've disabled the IMEx modules, because otherwise we are not able to compile psi-jami.
