Dynamically detect src dir and provide package builder

A way to dynamically detect wich directory the source exists in as well
as a builder that will easily build packages for use with push and
fetch. Greatly cleans up the push.go file and could be used with
fetch.go with some work
godep: include dependency source code

Flag -copy=false in godep will be removed. This commit
switches to using 'godep save' with no flag. We don't
change the version of any dependencies here, just rerun
godep to include source code.

See also the proposal for removing flag -copy at
http://goo.gl/RpYs8e.

godep: switch to -copy=true
sObject creation
================
Fixed issue about allways trying to add field when creating an sObject
even if no field was defined on cmd-line. The fields where also
attempted to be created twice. No field options where respected.

Custom Field creation
=====================
The NumberField struc did not contain all the fields and this stoped
creation of these fields. Numeric and float field does not support a
length attribute (API restriction). Member was removed from structs.

Display text where corrected. Length removed and description of Precision
and Scale seemed to have been swapped.

Fix ActiveLogins method to return no accounts

ActiveLogin was calling out to ForceLoginAndSave when no previous
history existed. Since ActiveLogin was being used by CurrentCredentials
to get the currently active endpoint, this caused the SoapLogin to
fail, always calling the OAuth login.
