Version mismatches in requirements.txt

[Kataract]

From a fresh install:

• Python 2.7.10
• pip 10.0.1

symposion 1.0b2.dev11 has requirement django-sitetree==1.5.1, but you'll have django-sitetree 1.8.0 which is incompatible.
symposion 1.0b2.dev11 has requirement django-timezone-field==1.3, but you'll have django-timezone-field 2.0 which is incompatible.
symposion 1.0b2.dev11 has requirement easy-thumbnails==2.3, but you'll have easy-thumbnails 2.4.1 which is incompatible.
keen 0.5.1 has requirement six~=1.10.0, but you'll have six 1.11.0 which is incompatible.
registrasion-stripe 0.1.0.dev6 has requirement django-countries==4.0, but you'll have django-countries 4.6.1 which is incompatible.

Does not prevent rest of installation. Have not tried to use anything that the symposion beta/dev version may rely on yet.
