i'm still not finished! please have it reviewed

this PR will allow to support more distributions other than alpine. using proot-distro as an engine

by default it will use alpine, by setting CNF_OS_TYPE variable to debian or arch will use that distribution

for remote uninstallation, just specify export CNF_UNINSTALL=1 to trigger uninstallation of the distribution

and to disable. specify CNF_DISABLE=1 variable

Well. That would better to do something else. Gonna test it out.

This command-not-found is better to put it to install.sh script. To be clever, The command-not-found code should be inside install.sh file instead.

maybe though i thought it would be better for install.sh to install files in directories

[Yonle]

Well, maybe writting those all fish script inside install.sh would OK. I may check it later
