Performance Optimisation.

Changes to improve performance

• Changed date generation for date tag value
• Added loading screen
• Added "maximum items displayed" drop-down
• Additional change from using locale functions to get day name for tags, to using a static list in config, which took another half second off processing time. This has the disadvantage that it needs a list in config, but has the advantage that the day names are fully customisable.

Good spot! This was caused by the change from using locale formatting functions to just formatting hour and minute. To get the timezone code, it renders one date and extracts the timezone code. I used the epoch date of 1970 for this, which seemed to work fine for most timezones, but missed that it had problems for some, possibly if they had changed their timezone some time in the last 50 years. I've changed to using the current time to get the correct timezone code. I think this might have some problems around daylight saving changeovers, so I'll continue to look at ways of improving this.

Initial load wasn’t as snappy as Peter had hoped, but performance when navigating back to the schedule is significantly improved on the Chicon schedule.

Thanks for the feedback. I think there are a couple of areas we can improve things further, so I'll work on it over the next few days.
