JPPM: Tries to download GitHub packages in /opt/download, when running as a normal user

[NyaomiDEV]

naomi@naomi-PC:~/jphp-test$ jppm add preg@git+https://github.com/TsSaltan/preg
-> linux
-> add 
-> get versions of package preg, source: git+https://github.com/TsSaltan/preg
(info) -> Download Package preg@master from 'git+https://github.com/TsSaltan/preg'
(error) Failed to create directory '/opt/jppm-0.6.1/../download/git/github.com//TsSaltan/preg'
(error) Failed to add 'preg@git+https://github.com/TsSaltan/preg', is not found in repositories

I should be able to add and remove packages without needing to be root.
