Sending macros over Bluetooth

[msvisser]

Sending macros over Bluetooth currently does not work when the macro contains more key presses than what fits in the UART transmit buffer. This issue was attempted to be solved in commit 2dde284, however this introduced other problems with the Bluetooth as described in #14. Therefore the changes were rolled back in commit e3e9355.

Any suggestions or possible fixes are welcome!

Mby we could create a bigger buffer of about 1024 bytes that receives the macro, then cut it in 256 sizes , so it fits in the tx buffer and transmit the 1024 in 4 times of 256 bytes. This could be a bit slow but as long as we are not able to change the uart conf , i think is the only way.
