Began using org-drill to remember coding and emacs hotkey facts.

Added a couple of really bad+simple yasnippet snippets to assist in
fast fact making.
Add to LD_LIBRARY_PATH rather than completely overriding it for
autocomplete.

This fixed location issues of clang (e.g. ~/build/llvm/bin/clang )
Should probably investigate usage of -Wl,-rpath,PATH for this instead.
Added smartness to tizen helpers:

variable to use choose whether to use env http(s)_proxy when invoking
wget

improved selection of an image file for install thru sdb
