CDB-2891 Merge error + wrong schema_path
CDB-2891 Bad merge fix
Do not create "the_geom" field at import time

Fixes forcing "polygon" spatial type, closes #547.
The "the_geom" field is still created later, at cartodbfication time.
CDB-3094 some helper methods in user model related to organizations
CDB-3094 assigning database and schemas based on whether the user belongs to an organization or not
Consider the following lines as a way to create a couple of users and assigning them to an existing organization:

```ruby
org = Organization.first

foo = User.new
foo.email = 'foo@cartodb.com'
foo.password = 'testing'
foo.password_confirmation = 'testing'
foo.username = 'foo'
foo.database_schema = 'foo'
foo.organization = org
foo.organization_owner = true

foo.save

org = Organization.first

bar = User.new
bar.email = 'bar@cartodb.com'
bar.password = 'testing'
bar.password_confirmation = 'testing'
bar.username = 'bar'
bar.database_schema = 'bar'
bar.organization = org

bar.save
```

Right now:
foo user cannot import tables from common data but can create tables from scratch that are properly cartodified
bar user cannot import and tables created from scratch are not cartodified
Merge pull request #550 from strk/donot-force-polygon

Do not create "the_geom" field at import time
CDB-3094 Enable sharing tables using cartodb.CDB_Organization functions

Consider the following example to share the first table from user foo with user bar

```ruby
foo = User.find(:username=>'foo')
bar = User.find(:username=>'bar')
foo.tables.first.add_read_permission(bar)
```
