E2 Editor: Blocked typing backquotes
The key is the default open console button, and has no use in E2
If you for some reason want to write it in a string or something, copypaste it
E2 Editor: Optimized EDITOR:MovePosition
This is inherently a really slow function on large E2's, but now its 50% faster
E2 Editor: Heavily optimized double click word highlighting
This lowered cputime during a highlight in a 300kb E2 from 2 seconds to 0.02s
Fixes #445
Added a universal Wire toolscreen
Rather than quickly scrolling the name of the tool, trying using various sizes
#338
Added convars wire_tool_worldweld and wire_tool_nocollide
These replace the checkboxes in individual tools.
They can be set in "Wire - Tools" -> "Tool Options"
Welding can be disabled by holding Alt while spawning.
Added these convars to the Tool Screen
#370
Toolscreen: Added spawnicon
More because its cute than for practicality
Removed a few more refs to tool's collision checkboxes
Closes #431
Change various e2 round functions to use garry's

Change the round functions for numbers, angles, vectors and vector2s to use garry's round function instead of computing it.
On my machine it's even faster this way, for Nebual it appears to be slower.

Either way, the way it was computed was erroneous and sometimes gave strange results.

Fixes #446
Merge pull request #448 from Xandaros/patch-1

Change various e2 round functions to use garry's
E2: Optimized round/ceil/floor functions
Also fixed some Vector2 functions returning Vectors
Changed round(A,A) -> round(A,N)
Followup to #448 and #446
Added a Version Checker on startup and concmd 'wireversion'
Concommand works clientside (prints the server's version)
Can detect Workshop, Git, and SVN (at least TortoiseSVN)
The partial git hash works in https://github.com/wiremod/wire/commit/f3a4ac3
