BashRC: Added a new TERM_APP environment variable to detect the terminal host app. Added a catnl helper for fast string embedding. VimRC: Added more swap words and a new Ruby tooling (:CA) which creates missing alternate files. Also the NERDTree plugin collection was increased and basic tooling for Github links was added. Last but not least the Vim performance (boot and runtime) was improved by not using a Bash login shell.
