A couple of corrections

* Add "\t" to stuff we filter out of content in XML Parser
* Up the production icon limit for phase_village, phase_city row
* Adjust width of structree page dynamically, rather than keeping it at 1000px wide regardless of screen width
* Enforce coding standard
Mark object keys for translation
Mark strings for translation
Capital -> Big-First-Letter SpecificNames consistently

* If a word starts with a Capital Letter, that capital should be made a Big Letter when that word is presented in Small Caps
* This is in keeping with other parts of the game's UI
Add JSHint tags for code quality testing

Brackets commented with "E084" are brackets that shouldn't be there to comply with 0AD's code standards, but are required for JSHint to recognise the encapsulated `let`s correctly
 - Known P1 bug in JSHint, issue 1862, possible resolution in 1910
 - "E084" is the relevant JSHint error code that shouldn't appear
Add README and update mod.json
