Grafana 1.5.3 released.Removed

Grafana version 1.5.3 has been released, featuring a series of small improvements and bug fixes rather than major new features, as the team has been focused on developing a new website. Notable additions include a new error inspector for addressing "Oops! Graphite HTTP Request Error" messages, which provides detailed request and error response information through a view details link. This release also enhances InfluxDB support with features like using aliases and improves scripted dashboards by allowing asynchronous dashboard scripts with tools such as jQuery AJAX calls, enabling the creation of more dynamic dashboards.
