new version id for monero PR#3526 (#215)

* new version id & name
* witness checksums
* build docs updated for v0.12
* remove binaries
* setenv HOME for ringdb to 'monero' in shared storage
* min ringsize 7
* remove boost_locale and zmq from build - don't need them for wallet_api
* splits for all archs
* throw IndexOutOfBounds in case the TX is empty
* donate, you ungrateful bastards! (removed donations to make google happy)

 You may lose all your Moneroj if you use this App. Be cautious when spending on the mainnet.
 
 ### Random Notes
-- Based off monero v0.11.0.0 with PR #2289 applied
+- Based off monero v0.11.1.0
 - currently only android32 (runs on 64-bit as well)
 - works on the testnet & mainnet
 - sync is slow due to 32-bit architecture
 - use your own daemon - it's easy
 - screen stays on until first sync is complete
-- saves wallet only on first sync and when sending transactions or editing notes
 - Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/
 
 ### TODO
-- review visibility of methods/classes
-- more sensible error dialogs
+- see taiga.getmonero.org & issues on github
 
 ### Issues / Pitfalls
-- The backups folder is now called "backups" and not ".backups" - which in most file explorers was a hidden folder
-- Wallets are now created directly in the "monerujo" folder, and not in the ".new" folder as before
-- You may want to check the old folders with a file browsing app and delete the ".new" and ".backups" folders AFTER moving neccessary wallet files to the new locations. Or simply make new backups from within Monerujo.
+- You should backup your wallet files in the "monerujo" folder periodically.
 - Also note, that on some devices the backups will only be visible on a PC over USB after a reboot of the device (it's an Android bug/feature)
 - Created wallets on a private testnet are unusable because the restore height is set to that
 of the "real" testnet.  After creating a new wallet, make a **new** one by recovering from the seed.
