Event listener to update gists on save when supress_save_dialog is true (update for sublime text 3 support)
added new setting to control the save-update hook.
update_gist is put into a thread so that sublime doesn't becomes unresponsive on-save
save on opening a gist (to a temporary file) so we don't have a chance of reloading an older version of that file.
Fixed a bug where the gist is updated automatically upon opening
handle error when opening settings file
handle error for missing globals
Fix issue with uninitialised globals in a way which works in both versions
Fix thread issue (API functions cannot be run from non-main thread) in sublime text 2
taken out ternary operators from complicated expression
A little styling
save-update-hook description in README.md
