New theme engine with full i18n (WIP)

How the new theme engine will look like on first iteration IMO:

theme.json file inside Themes subfolders (may change to named subfolders or keep numbering
easy menu reordering, since most of the menu.c logic goes inside separate gui.json (maybe some other info too).
keep menu looking similar to current one BIOS-like 3-level:
Top ribbon options
Suboptions in the left half
Description or suboption item selection on the right half.
all strings links to lang files items
background images are optional and can be customized for each menu and submenu

[x] Additional 24px bitmap unicode font for ribbon menu captions and future use
[x] Lang engine redesign with no string names, that also allows English UI with no lang files at all
[x] Make draw string with auto line wrap
[x] Make gui.json parser
[ ] Modify current language files with english strings as a keys and no '\n' - help are welcome
[x] Change Launch menu to Boot and gather Boot sysnand, emunand, pasta, reboot and shutdown options here
[x] Make theme.json parser
[ ] Switch config to abstract keys and type-independent values to easily link with menu options display
[x] Gather theme selection and random theme under one option in settings with theme names also listed (random theme not implemented yet)
[x] Gather autoboot options in one settings menu (no, emunand, sysnand, pasta)
[x] Exclude 3D UI option from settings, since actual top screen background images will be defined in theme either with single or stereo files
[x] Add autoboot override button selection setting
[x] Move emu/sysNAND selection to separate menu items
[x] Use system font from 3DS NAND
[x] Batch processes time estimation instead of just percents
[x] Exclude external cryptographic library dependency
[x] Add SHA hardware engine
[x] Refactor AES hardware engine (WIP)
[ ] Unified NUS files location (WIP)
[ ] .tmd-based NUS files processing (WIP)
[x] Add NCSD-header based *NAND partition processing
[ ] Refactor all current tools
[x] Add SD MBR-based multi emunand support
[ ] Add patch profile
