Started implementing packages

util is now 'indigotock.btools.util' (get via Apollo.GetPackage). Also
one minor fix relating to variable names
Brought over xml forms

Created new forms.xml with elements for number ticker, search list and
drop button
Removed main btools.lua

Apollo requires the use of packages so it's useless
Implemented number ticker

Fully implemented the number ticker from the old version along with some
minor bug fixes
