CONFIG_FILE filename collides with intellinote client config file on case insensitive filesystems

[pstaender]

Hi,

I'm using the desktop app and the cli api client on mac os x (with case insensitive file system hfs+) and the config file of intellinode-cli (/Users/user/.intellinote) collides with the config folder of the desktop app (/Users/user/.Intellinote).

Proposal: a configurable env variable like process.env.INTELLINOTE_CONFIG_FILE

CONFIG_FILE = path.join(TILDE, process.env.INTELLINOTE_CONFIG_FILE or '.intellinote')

or check if folder exists and store config file in $HOME/.Intellinote/.intellinote. This will also occur on windows I guess.
