Added new config setting timezoneOffset, usefull when your graphite server is on a different timezone thant your users browsers. This is not optimal (for example if your users have different timezones) can be improved by finding a way to query the timezone different between browser and graphite server. Or fix so that the &tz graphite parameter works for json, then all absolute filters can use UTC time.  #31

Update graphiteSrv.js

Fixed graphite import to include all graphs in a dashboard.

If 'now' is not in 'data', the result is -1, so it should be '>= 0' ...

Sets graph title when importing from graphite

Fixed typo in import

Correct typo "probject".

Fixes #16 (Basic Authentication), set graphiteUrl: http://username:password@domain.com  and it should work, but requires special CORS settings in apache2

Partial fix for #10 , the lexer & parser can now handle curly brace, but target editor needs to be updated to support selecting multiple segment nodes

added more function definitions, added small hack to make randomWalk and countLine that do not take any series work with the parser and target editor (the whole target editor and parsing & back to target rendering needs to be rewritten to handle functions that take multiple series)
