add english flick layout

[Fuseteam]

here's how it should look like

this layout has less but bigger keys
the middle three colums of key can each input 5 characters each by tapping and flicking left, up, right and down; totaling 60 characters
the left and right columns contain cursor keys to move the cursor forward and back by one character
pressing and holding will activate cursor mode
the top left key is the caseswitchkey
this key can be pressed to change case, flick up for upper case, flick down for lower case and flick right for space
when in autocomplete/autocorrect mode tapping this key will change the case of the previous entered character, flick up will activate cursor mode, flicking down will input a new line and flicking right will input a space

@UniversalSuperBox review please

[Fuseteam]

The casekey now behave the same in autocomplete mode flick up to change the previous letter to uppercase, flick down to change the previous letter to lower case

known issues
the layout adopts the dictionary of the previously selected layout (#100 )
swiping up from the top row occasionally dismisses the keyboard partially (#111 )
there is no method for inputting "accent characters"
the "icon" for switching case is not intuitive
