Tab key should be mapped to 2 spaces

According to the Nim Style Guide, two spaces should be used for indentation of blocks, so IMHO the "tab" key should be mapped to 2 spaces instead of 4.

Snip actually supports multiple programming languages so I just set it to 4 spaces by default. You can always change it with keymap.txt:

TAB = TO_2_SPACES

Well... in my opinion most people are going to use snip as a Nim local playground, so it would be better to set 2 spaces by default (and change it for other languages), but never mind of course.
Thanks

Just to add...the Nim Playground has a default of 4 spaces, so it is consistent with that :)
I notice a fair few Nim users using 4 spaces also

Instead of conforming to Nim Playground, IMHO both should be updated to conform to the Nim Style Guide.

Fixed in #head - please try out.
