Option/script to download TTS from responsiveVoice/other in advance #188

For #161 and other reasons (notably that Bengali voice only available in ResponsiveVoice app - not iOS voices) - that we have some kind of script/tool that builds a mp3 version of a tree in advance (so downloads the voice results from responsiveVoice) - that way we can run on a device with limited TTS support - or for systems where online TTS is a bad idea..

Bit more info: Basically there is a worry that if we use Googles TTS (ResponsiveVoice API) - or any other additional Online API for TTS we will run into two problems:

Potential lag as it generates the voice on the fly
Need to be online

Also for anything other than spelling all items are currently fixed. I.e. nothing really needs to be dynamically generated. Couldn't we use a third party online TTS tool - but basically run it through a script to create wav recordings of all the words in advance?

Thats the idea at least!

NB: Maybe another issue - but basically using the inbuilt TTS engine on iOS leads to a problem as some voices aren't available. But they are if we use the inbuilt (Nuance system) PLUS allow access to another system (Googles TTS does provide us with a Urdu voice for example which we often need)
