Consolidated navbar and footer in main.html
Moved player check and redirect to chodewars.py.

This removes the need for the player to click on a link to start the player adding process, since this step is useless.
Fixed page title for adding a player.
Moved planet and ship creation to same form as player creation.
Styled the add player form.
Removed old 'add home sector' page.
Planets are now landable and scanable by default.

Closes #31
Cleanup and move warp-list to sector.html.
Can now land on and takeoff from planets.

This does a lot of housekeeping as well, moving some parts of the html template to their own file (specifically the entity-panel.html), which should help prevent duplicated code later.

For now, there is a separate file for rendering a planet (planet.html), but this will likely be combined at some point to a common render.html file.

Closes #8
Planets and Ships can now hold a population.

* Added habitable attribute to entities
* Added population and population_growth variables to entities
* Changed planet and ship to be habitable by default

Working on #9
Planets have a population by default.

* Planets have a default population of 1 million
* Planets have default population growth of 5 percent
* Planet display shows population

Closes #9
Merge branch 'aesthetics' into planet_interaction

This is required to test the previous commit.

Conflicts:
	templates/index.html
Fix the botched merge from the last commit.
Fix a copy-paste failure.
Added population count to planet entity box.

This also moves the size of the entity box to the entity-panel.html, so it would only need to be changed in one location.
