Issue with Kaya-cli and ../data

[csajedi]

I've been having several problems with Kaya on windows so now I'm using NVM and virtualbox in an attempt to bypass the issues. However, it seems that npm install -g kaya-cli will result in some problems regarding permissions in its relative path. Full output of my error:

~ kaya-cli -f

There is an open issue that may fix this by removing relative paths: #78 , but it may have gone stale. If we were to move to a database, what would it be? a sqlite DB stored in $HOME/.kaya ? If I have time in a couple weeks I may attempt a fix and submit pull request.

I plan to refactor it in Q3 to include a few features, including storing the state files in a database like leveldb.

Apologies but I haven't got time to work on it soon. But if you could make a PR, that will be good. A few users have complained about the kaya-cli and relative filepath issue.
