Kibi text editor as a replacement for nano

[vasilvas99]

Issue

Nano was removed as it is a GPLv3 component, which is a license incompatible with Apache-2.0 (under which meta-leda is relased)

Solution

Recipes for the small (and with similar UI to nano) text editor Kibi: ilai-deutel/kibi were added under a new components subdirectory - leda-tools.

Other:

• Since the syntax highlighting config files for kibi are small enough they are installed by default. (changed through the bitbake variable KIBI_SYNTAX_HIGHLIGHTING)
• Since it's supposed to be a nano replacement, nano is aliased to kibi by default. (changed through the bitbake variable KIBI_ALIAS_NANO)
• Kibi has an active community on github
