Added the ability to change grid type in Preferences, and made an isometric cell size value which affects just the size of the cells of the isometric grid. Also updated translations.
I mostly did it so I could move tile mode logic into a new node, so I could have control over the drawing order. TileMode.gd also always draws 8 blank rectangles, which are being drawn on top of the grid, in order to hide it if it gets out of boundaries. We are now very close to implementing an isometric grid, #305.
This shouldn't have much of a performance impact, but some more testing is most likely needed.
Instead of drawing individual lines, execute draw_isometric_tile() multiple times. What this method does is basically draws a single isometric tile, which then gets repeated for the entire canvas size. Also moved all the grid logic to a new script, which gets updated less often that Canvas.gd, for optimization purposes.
Works better than the previous method, although it might be a bit slower, and currently does not work well if the canvas size is not divisible by the grid size. For now, it only gets affected by the grid width. Changing grid height has no effect.
This comes with the benefit that we no longer need a Viewport node in the ShaderEffect dialog, which lets us have the Preview TextureRect at a fixed size. Previously, the preview was scaled based on the image's size, which would make applying shaders to large images very inconvenient, since the dialog would be way too big.
Not sure if options for RGBA channels are really needed here, but I kept them from invert colors. We could remove them in the future if they are unneeded.
* Split export code from export dialog to Export.gd autoload
Clean access to child nodes of export dialog
* Fix export variables set in Main.gd
* Fix more wrong variable assignments

If the loaded shader has uniforms, they will be exposed to the UI, so the users will be able to modify the shader parameters easily. Currently only works with float uniforms.
This new feature allows users to load a .shader file (must be a GLES2 Godot shader) that will modify the image itself. This feature is experimental and possibly buggy, not all shaders are working properly and I'm not sure yet why. As such, this feature may not be included in v0.8 stable.
