Arduino advanced features

- NTP (network time protocol), where the date/time is gathered from a timeserver in the internet; - http server access with username/password login to calendars directories (server and calendar directories configurable in constants in code - as well as time between downloads); - server calendar ICS files stored to distinct directories in SD card; - SD card ICS calendars parsing and detection if current time is within some of the periods defined in one of the calendar ICS files - *timezone not implemented - for now* - this is working with the current set of files on the server, might need testing with other files???; - RSS feeds download, parsing and data extraction to send for display. - display protocol and display update with data gathered from RSS feeds and calendar and parking free data; - implement algorithm to detect what is the opening_start_time/opening_close_time/opening_next_start - this will be the most difficult part for me, I think...; - implement the "timezone" function in the ICS files parsing and time handling functions; - find a proper way to deal with data encoding (german/english/portuguese/etc....) - some strings are bad-formatted and will need some fix; - integrate the previous project into this one (the parking free slots display); - general integration of all functionality. - advanced functions
