Changed how mounts are determined for flying/land as the coming changes in Cata. It now keeps a global list of all mounts and what they can do (land/flying/both/swimming).

Added Aufenthaltsort for german translation (location) for celestial steed and if in german client they start adding this for mounts that can be used everywhere (unfortunately, english has location for HHM/Celestial steed, but german didn't until Celestial Steed). X-53 should work across all clients, as X-53 is not a word.

v3.0.1
Added German Translation for specific keywords, thanks to: Brenainn

v3.0
Added Sea Turtle cast if swimming to random mount, otherwise a land mount is cast. Added Acquatic form if swimming and druid.

Updated ToC to 3.3

v2.8
IsFlyableArea Does not work during Combat in WG, added code to correct this.

IsFlyableArea() was fixed in 3.2 and properly determines if you can mount. Simiplfied code this way.

Minor fixes to color code.

v2.6a
Fixed issue with next button on GUI not re-enabling when prev button was pushed, until page 1 was reached.

v 2.6
Began chinese translations.

v 2.5
Updated so no error message (found the API call to find out if WG is in combat and was able to see that land only during combat, flying every other time, even if other faction owns WG, sorry took me a bit to have time to test). Updated Druid travel forms for WG hopefully, need someone to test.

v 2.4
Updated for flying mounts in WG, what it does is try to mount a Flying mount then a land (in case of battle). So you will get a message another action is in progress, or you can't use that here and a land mount is summoned. Unfortunately, this is due to the fact that CallCompanion doesn't return anything (ie success or fail). Also, i did this cause I wasn't sure if you can mount you flying during WG battles. Been busy, haven't been able to test.

v 2.3
Updated TOC for 3.2

v 2.1a
Fixed code for the druid forms again.

v 2.1
Hopefully fixed the profession only mounts and headless horseman mount.

v 2.0d
Hopefully re-fixed the druid forms.

v 2.0c
Was pointed out to me, that I shouldn't use global variables, but use a table. This has been fixed. However, your mount list will now be blank.

v 2.0b
Hopefully fixed the druid forms.

v 2.0a
Hopefully fixed the cat form inside toggle command. Also added a check if the player is a druid, so it will just tell you to ignore that command if you are a druid.
Hopefully fixed the not using flight form in flyable areas.

v 2.0
Added localization, enUS only right now. If you want to contribute another language, please look at the localization.enUS.lua file and there are all the variables used within MRM. Send me a comment that you would like to do this.
Added shaman/druid ability to use GW/travel/flight forms. It uses a 3rd binding for this, since they are considered spells and not mounts, a secure button must be used. So they can't be part of your random list. The 3rd key binding will show up for non druid/shamans but if you set a keybinding to it will display a message you aren't of the right class.

v 1.2
Fixed the problem with not mounting up a land mount if you had no flying selected.
Added a binding to mount a random land mount only (for those times you want to show off your land mounts in flyable areas)
Added a command to reseed mount ID's. If you play on 2 computers and you learn a new mount on 1, your list on the other won't work correctly until the ID's are corrected. This will do that.

v 1.1a
Was not correctly updating your list when a new mount was added. Fixed.
Will have to clear your list or add a new mount.

v 1.0
1.0 release
GUI added
fixed an error where no printing of what mount was added when your flying or land list is empty.
Added keybing

v beta .5a
Changed it so that a flying mount would be used in Krasus' Landing in Dalaran.

Just seeing if I can get this working. Don't expect anything.
