Updated to v.1.4

1.4
- NEW APP ADDED: KindleTask 0.1
I made this tiny new app (10kb) to replace in a native way Yad task manager,
that didn't work on PW2. Screenshot below.
- Overall speed improvement , especially in app launching. I fixed a little bottleneck that didn't see before
- Fixed alert timing small issue
- Battery button now works as an ON/OFF switch, not ON only (like it did before instead)
- Fixed kterm layout when launched from landscape mode
- Recoded some javascript for better performances and readability
- Fixed Exstensions launcher issues with some script ("light toggle OFF
on wakeup" excluded. For now, just don't launch it from Kindle Menu)
