Updates URL for PressCrew in readme.txt. Fixes #64
Install CBOX Theme on BP_ROOT_BLOG.

If BP_ROOT_BLOG is defined, make sure the CBOX Theme is installed there and
not on blog ID no. 1.

Fixes #65.
Update 'Theme' section on CBOX dashboard to reflect root blog install
changes.

See #65.
Change 'Dev tracker' link to 1.0.x branch on Github.
Create generic 'CBox_BBP_Autoload' class.

* This class will house all hotfixes and workarounds for bbPress.
* Move 'CBox_BBP_Site_Public' class code into this new class.
Add workaround for bbPress 2.2.x's dynamic role setter.  Fixes #61.

bbPress 2.2.x's role setter conflicts with blog creation on multisite.

bbPress 2.3 addresses this, but the fix was not backported to 2.2.x.
Therefore, we enforce our own hotfix.

Props @boonebgorges.
Update cbox_is_theme_bp_compatible() to use BP 1.7 logic.

* Replace bp_get_template_part() function check for BP_Theme_Compat class
  1.7 abstraction layer.

* Removes 'buddypress' theme tag check and BP Template Pack check

* Replace with BP 1.7 logic
  * Check if theme supports BuddyPress with current_theme_supports()
  * Next, check if theme is a derivative of bp-default
  * Lastly, check if a theme bundles the members loop template.  If this
    template is found, we can assume the theme supports BuddyPress.
Update CBOX badge CSS styles.

Relax CBOX's default GES setting so it isn't forced.

Previously, CBOX's default GES setting of 'All Mail' was overriding the
group's own defined GES setting if a group admin wanted to change it.

This commit only forces the 'All Mail' setting if the group's setting does
not exist.
