Erased almost every instance of WORLD_SIZE and replaced it with a local
power of two, map_size_lg (which respects certain invariants; see
common/src/terrain/map.rs for more details about MapSizeLg). This also
means we can avoid a dependency on the world crate from client, as
desired.
Now that the rest of the code is not expecting a fixed WORLD_SIZE, the
next step is to arrange for maps to store their world size, and to use
that world size as a basis prior to loading the map (as well, probably,
as prior to configuring some of the noise functions).
If the mainhand slot is swapped out or dropped while the character is
wielding, the character will be set to idle (same behavior). However, if
an item is picked up or used; or a non-mainhand item is dropped; or two
non-mainhand items are swapped; the character state will not be set to
idle (new behavior).
Rationale for keeping the same behavior:
Swapping a weapon out while in a wielding state can put the player in a
barehanded wielding state, which would be inconsistent with the fact
that that state can't be entered by toggling wield while barehanded.
Rationale for setting the new behavior:
Setting character state to idle was originally added because "Interact"
was mapped to right mouse button, so picking up an item with RMB would
also activate secondary attack if the player was wielding during the
interaction. Now the default keybinding for "Interact" is E, so this
isn't a problem unless the player changes their keybinding to RMB.
In addition, setting character state to idle for any inventory
manipulation may cause players to fall out of glider unexpectedly.
- replace serde_derive by feature of serde
incl. source code modifications to compile
- reduce futures-timer to "2.0" to be same as async_std

- removed mio, bincode and lz4 compress in common as networking is now in own crate
btw there is a better lz4 compress crate, which is newer than 2017
- update prometheus to 0.9
- can't update uvth yet due to usues
- hashbrown to 7.2 to only need a single version
