Array against POSIX

[francescobianco]

Actually, the BPKG_REMOTES variable around the project is used as Array, this is hard to convert into POSIX compliant solution due to missing of good array management into shells like Dash or any other POSIX-sh.

To work it around we can use a comma ',' separated list into a standard string variable

define -a BPKG_REMOTES
BPKG_REMOTES=(a b c) 

become

BPKG_REMOTES=a,b,c

What is your opinion about it?
After my last revision of install.sh this seems the major blocker to convert the entire file into POSIX compliant
