flag_friend 6.x-1.0-beta1

Changes since DRUPAL-6--1:

• D6 port
• fixing the persistent set message
• - removing persistent set message on inappropriate pages.
  - do not save the message during accept, just email it.
• -fixing bug in the approval process.
  - fixing typo.
  - reordered some commands.
  - alter flag link so we cannot flag ourself as a friend.
  - removed not about patching. default flags are now in flag core, dev.
• adding views integration. removed hook_menu implementation and subsequent page callbacks
• Adding specific category to hook_user op:form for display of our setting.
• adding popups support and updating default view to include the message as a default field.
• adding user check in _init() before calling any flag for flag_friend functions.
  also added in a helpful note on install.
• cleaner way of removing the link on your own account view so that you cannot flag yourself.
• After using on a production site, I've made some changes to the module that benefitted the site and should benefit others as well.
  - flag_friend_determine_friend_status() now has the ability to reset the caching. was having some problems related to not being able to do so.
  - changed default pending text, will make this customizable in the future.
  - added a css class to the 'unfriend' flag and gave it the unflag title.
  - removed the persistent drupal_set_message as this is kind of annoying. will reimplement with a setting if requested by anyone.
  - friend notification setting title and description look better and fit with other account setting formats.
  - better checking for unfriend, hopefully fixes a few of the reported bugs.
  - status check global has been changed due to the caching mechanism.
  - updated the default text for the default flag to include the [user] token.
  - using reloadWhenDone in hook_popup as the content target that popups does is not always reliable. I'd rather refresh the page then the incorrect content area.
• correct table prefix support by jaydub
• adding correct translation within our drupal_set_message(). thanks jaydub and andypost
