Added anywhere bash functions.

anywhere moves the specified file/directory to /opt/bin so that it can be executed
from anywhere in the filesystem.
Added readme for my personal notes.
Merge branch 'master' of https://github.com/skytreader/.files
Added --global tag for git config core.fileMode .
Added bash function anyscript.

Along with previously-added anywhere, use it to keep your /opt/bin/ directory
organized.
