New scrpit: spell-commit

Checks spelling in commit content and message. Splits CamelCase and
uderscore_delimited words for best results in source code. Does not
show any words found in prevoius commits as miss-spelled. Dirty as
most bash scripts, but works for me.
New script: gh-link

Generate github link to a line in a file in current commit of current
project. Can yank it into X clipboard if xclip binary is available.
Especially useful when bound to hotkey in an editor.
